I recently cleaned up my PC and been reinstalling stuff. I reinstalled Fallout 4 yesterday, but when I updated to patch 1.5.. boom, constant crashes. the game won't even start. and before you ask, no I don't have any mods installed. I googled all night and every solution is about ui mods or whatever. but no one replies when people without mods installed ask the same question.. any help here? thanks in advance!
