Plutonium

Open powershell, copy and paste this:

Set-ExecutionPolicy unrestricted

Press enter. Type "A" without the quotation marks, press enter.

If this worked, after you're done playing, open powershell, copy and paste this:

Set-ExecutionPolicy restricted

Press enter. Type "A" without the quotation marks, press enter.

Unrestricting the execution policy allows any .exe to do whatever it wants. Error 0xc0000005 is an access violation error when a .exe is disallowed by Windows to execute something.

And open your firewall settings to allow an app through the firewall, tick plutonium-bootstrapper-win32.exe and press "Ok".

That error can happen when the .exe needs to read a config or system file. You might be missing essential files the plutonium-bootstrapper-win32.exe needs in order to run.

Windows cannot access the file for one of the following reasons: It could be there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on the computer; or the disk is missing.

I would suggest you delete everything inside "C:\Users\You\AppData\Local\Plutonium"
Delete your plutonium.exe and download a clean one from https://plutonium.pw/docs/install/
Run it as admin and let it download all the files/dependencies again.

Can you upload the crash dump file? You can do this by pressing the button next to the quick reply button. It opens up a composer with a bunch of other options where you can select to upload a file.

It does seem a lot of others are suddenly having this crash issue, I imagine Pluto's aware of it and trying to fix it.

ZirFox80s Does it do it only on that 1 custom map or across mulitiple others?

Try downloading a new plutonium.exe, don't run it yet though
https://cdn.plutonium.pw/updater/plutonium.exe

Delete the previous plutonium.exe

go to C:\Users\Xacob\AppData\Local\Plutonium
delete everything inside.

open up notepad.exe, copy and paste this into it, save it as "systemhealth.bat", run it as admin and wait for it to complete, then restart your pc:

@echo off
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ipv4 reset
netsh int ipv6 reset
netsh int ip reset
netsh int tcp reset
pause

run the new plutonium.exe

this happens if you type into the console "resetstats" which resets your online stats/save data for the zombies/multiplayer maps.

i'm guessing you have a .gsc script which, when loads, resets your progress so that the easter egg can always be redone for fun. however, if you want the progress of the easter egg to stay, you'd have to find a different script which doesn't reset your stats.

if you go to bo2 modders and resources, click search and type "solo", set the category to "bo2 modders and released", it will list a bunch of released scripts people have made for soloing easter eggs. i've tested a few starting from the top of the list and they do what you're requesting, to save progress. however, if you ever want to reset the easter egg progress to do it again, you're gonna have to remember to type into the console "resetstats"

download and extract
https://github.com/yaboi-zombies/BO2-Full-Solo-Mods/archive/refs/heads/main.zip
drag the folders out of "zm" and put them into "C:\Users\You\AppData\Local\Plutonium\storage\t6\scripts\zm"
edit the file-names inside each folder so they all start with "zm_"

download this tweak and put it in the transit folder.
https://github.com/yaboi-zombies/Tranzit-Maxis-EE-Solo-Tweak/raw/main/Tranzit-Maxis-EE-Solo-Tweak.gsc

You could try this:
go to C:\Users\You\AppData\Local\Plutonium

delete the entire Plutonium folder and then run plutonium.exe so it all downloads again. Remember your login.

If that didn't work, it might be your firewall. When a firewall is triggered by an app, the firewall immediately terminates it. It gives no explanation why, just terminates the app. That's how the Windows firewall is.

In this case, you could try this:
Type "firewall and network protection" in the windows search bar and open it.
Select "allow an app through the firewall".
Scroll down until you see "plutonium-bootstrapper-win32.exe".
Select "change settings".
Select "plutonium-bootstrapper-win32.exe" and tick both boxes.
Press "Ok".

personal statement: if you can't get your game solo-able, don't sweat it, you're not missing out. the easter eggs are anti-climatic. that easter egg is just a sparkly pylon and then you go back to running around killing zombies with nothing to do until you die. it's quite depressing. lmao

Thank you to Resxt and Hadi77KSA for helping me understand how all of this works.

What you need to know:

1. .gsc scripts are what you're gonna use.

2. Be aware that some scripts just don't work anymore. Be aware that YouTube videos showcasing solo easter egg tutorials aren't fully accurate. Use the official wiki:
   Tranzit: https://callofduty.fandom.com/wiki/Tower_of_Babble
   Die Rise: https://callofduty.fandom.com/wiki/High_Maintenance
   Buried: https://callofduty.fandom.com/wiki/Mined_Games

3. The folder where your .gsc scripts go:
   AppData\Local\Plutonium\storage\t6\scripts\zm
   All file-names must start with "zm_" for Pluto to load them.
   Example:
   zm_tranzit.gsc
   zm_dierise.gsc
   zm_buried.gsc

Plutonium will try to load all .gsc scripts in "AppData\Local\Plutonium\storage\t6\scripts\zm". A lot of scripts aren't coded to check what map it is before they execute code. If a script meant for another map is loaded, it will cause errors and return you to the main menu. To get past this issue, you can create a folder for each map but the folder name matters.
Example:
zm_transit
zm_highrise
zm_buried

Yes, the folders have to be spelt that way. They are not typos. Plutonium will check if the map is Tranzit and then scan through "AppData\Local\Plutonium\storage\t6\scripts\zm". It will load the scripts found in "zm_transit" and skip the other folders. Remember, file-names must start with "zm_".

4. To reset easter egg progess, you need to open the console at the main menu and type the command "resetstats" and press enter. To open the console, press the ¬`¦ key (usually located below the esc key).

5. Find a .gsc mod menu to make your life easier testing easter egg scripts.

Here's an image of me on Tranzit finishing the Maxis easter egg solo.

Resxt I'm unable to edit my post due to the 3600 second rule.

Can you change the 2nd sentence where it says "LAN" to "solo", and then at the bottom where I've put a note, delete where it says "(LAN mode)"?

oh, so you don't need to be on LAN mode for the scripts to be loaded? i can just press "play" on plutonium, select solo and the scripts will work?

Resxt thanks but pluto's documentation for doing this isn't clear, in my opinion. this post might be easier to understand, and it will come up when searching the forums.

not sure what's unclear in the post so if you could explain that'd be appreciated. i just did all these steps in my post to know this is what works.

your mod menu must be .gsc, not .gscr

plutonium has a safe way for you to install a mod menu on bo2 for LAN mode. when you have a .gsc mod menu, put it in the following location:

C:\Users\You\AppData\Local\Plutonium\storage\t6\scripts\zm

your .gsc file must start with "zm_"
example: zm_modmenu.gsc

i don't know why, that's just how it is. here's what you're gonna do:

1. find a .gsc mod menu
2. edit the name of the file to have "zm_" at the beginning of it
3. put it in C:\Users\You\AppData\Local\Plutonium\storage\t6\scripts\zm
4. enjoy

note: when you load the game (LAN mode), you might select the in-game option "mods" expecting to see it listed there. it won't be, so go in the game and test the mod.
