Plutonium is its own app, it's not a software like the other you could download.
You have two solutions
First solution: if you want to download it to another drive you can either create a symbolic link which basically makes Windows think it's on C: (so that nothing breaks) while actually storing the files on D: for example
This example should guide you https://plutonium.pw/docs/modding/moving-to-another-drive/
Second solution: if you really want to install Plutonium on another drive I think you could use something like this in a bat file. Just make sure this bat file is in the same folder as plutonium.exe
@echo off
set installDir=D:\Plutonium
plutonium.exe -install-dir "%installDir%"
Also you should play in windowed borderless, not fullscreen.
If you play in fullscreen and alt tab you will very likely crash at some point
And yes everythng you sent is useless because these are just dev/mappers warnings, they're not errors
You might be experiencing signs of hardware failure if repairing the game didn't help. Try to use DisplayDriverUninstaller IN SAFE MODE and do a full uninstall of your gpu drivers then install the latest ones. If problems still persist try moving the game to another drive on your computer since your drive could be failing. It's also possible that data is getting corrupted by your motherboard when it's transfering data from the drive to the cpu package or from ram. This is however unlikely as your drive is more likely to cause this form of problem.
