@notsimpl this is what is contained in the .txt files don't you have crashdump files too? Should be a lot of mb, around 1gb. I can't really help with these error codes but I'd say try to unplug any unnecessary device (VR headset, controller, other monitors etc.) only keep main monitor keyboard and mouse to see if that could be your issue. Also make sure there are no software with an overlay running as it'll conflict with Plutonium's overlay and crash the game.
Last question: what is your antivirus? Maybe try adding both Plutonium folder and BO2 folder as exclusions too, you can do so by reading this guide.
