Game launches to load screen then crashes. I have a Vega 64 and an i5. Couldn't find the crash logs, tried reinstalling the game multiple times, and I've turned off all mods/DLCs. I'm really at my wit's end.
Is the loading screen displayed without any text? That often means that one of your savegames is corrupted. Try to move all your save games to a different folder and test if the game starts then. If it does, you can move your important saves back one by one to see which one crashes the game.
