I have fixed mine finally. This was also accompanied by random crashing and not being able to extract. I upgraded from A7.3 when I started having issues. Discord would also crash on me randomly while playing, sometimes at the same exact time, like my whole computer froze up. Never had issues like that from multiple different programs.
-I cleaned all the temp files and registry keys from the launcher
-turned off the Discord overlay
-I completely erased my SPT-AKI folder (except my profile)
-copied it again fresh from my official EFT folder
-installed B3
-did all the windows updates I haven't done (.NET framework was the more important one)
-started it back up and it now works perfectly with no errors
I tried changing notification settings, downgrading and retrying, updating my video drivers, nothing really did anything (except give me better fps lol) until I started from scratch.
Hope it helps you out as well.
