Plutonium

Can you use a VPN to check if the GFW is causing it?

ke_luo_zi no.You may want to search for "Alterware IW5"

ke_luo_zi If you own the game on Steam you can use whatever language you want. Just change the language in Steam and your game will have the langauge you selected.

ke_luo_zi idk what that involves doing, if you just replace files in the game folder so your game is in a different language it'll be fine with pluto. this bgt5 stuff works separately from pluto too so it won't get you banned. I would still recommend downloading clean files from here: https://plutonium.pw/docs/install/#installing-the-base-game-bo1

@SCPSUP steam_api.dll being deleted is normal. Plutonium deletes this to avoid conflicts with Steam afaik. The crashes might be caused by your antivirus. Try to add both the Plutonium folder and your BO2 folder as exclusions. See this guide

If that doesn't fix your issue then you might have to uninstall your antivirus. FYI Windows Defender the antivirus that comes with Windows 10 is very good for the average user and is free so I recommend that you stick with that.

@SCPSUP What do you want to do with it? You can pretty much place almost any weapon in the fridge and put up to the max $250,000 in the bank.
