I'm having a similar problem. The game ran like a charm yesterday, and I had been using NMM along with about 5 or 6 mods the whole time I played it yesterday without issue Today, I uninstalled the classic dialog menu mod before booting up the game for the first time. When I launch the game, it crashes within 5 seconds. I tried uninstalling NMM along with all the mods, restoring the ini files to their original state, running the game in windowed bordered/borderless, and both downgrading and upgrading my graphics drivers, but with no luck. EDIT: More info: I read on Reddit that save files can corrupt, causing the game to crash. Tried deleting my saves, no change. Also, tried OP's fix (moving/deleting ini files so new ones would generate), no change My rig: Windows 7 Intel 4690k 970 GPU Direct X 11
