i dont know if the fix is the same as a problem I had (but this was my live tarkov having an endless loading screen), but in the Documents/EFT folder, open the shared.ini file and find FOV and set the value for 20 or less. (recall something to do with the patcher downgrade). again, not sure if that would work, but it fixed my live tarkov endless loading.
Thank you so much, i was stuck on an endless loop on live tarkov and this fixed it. I wonder why changing the FOV fixes this?
