I'm experiencing the same issue, everything works fine, but what seems to be the issue for me is downgrading tarkov, once I downgrade from 13.9 to 13.5 on the spt launcher, it then says I don't own the game. When I go back to the tarkov launcher, it then tells me the game version doesn't match the live build, so the game needs a repair and needs to be reinstalled.
