[MODDED] Getting an error after updating to 3.6.0 - "Exception has been thrown by the target of an invocation"

I stopped playing tarkov a while ago (SPT was still in 3.3.0 iirc), and yesterday I suddendly felt the urge to play the game again, so I updated the game and SPT, after a few hours waiting for the game to update I tried to play using my old account but it didn't work, it gave me the "exception has been thrown by the target of an invocation" error while loading my profile, I tried to close it but after a few seconds it would pop up again.

what i've tried (apart from the stuff mentioned in the FAQ):

removing mods

creating a new account (error pops up after selecting my character's head and voice)

reinstalling tarkov

reinstalling spt

changing both live and spt directories

unchecking read-only attribute from tarkov folders

starting both server and launcher as admin

cleaning game configs and temp files

i'm currently using the latest win 10 update (as of 06/08/2023)

i never got this error before and i couldn't find anything related to it online (except for a few posts, but they weren't related to tarkov)

as i said in the post, i already removed all my mods and performed a clean install, nothing worked

i just opened the game again and it started working normally after i set the eft process priority in task manager to high, i honestly have no idea if this is a permanent fix but it worked
