My game instantly crashes once I leave Helgen Keep. There's no error or any sort of notification afterwards. I even enabled crash logs, but the logs aren't being generated so it's difficult to diagnos the issue. Does anyone have any ideas? Thank you.

Edit: I installed the "Alternate Start - Live Another Life" mod to bypass that part and start in a different location, but I also immediately CTD when outside elsewhere.

Edit 2: Logs are now being generated. However, no solution.

Sounds like a mod conflict. Does your game have any problems with a new game when you have no mods installed? That is the first step to finding the problem.

Can you list your mods?

I have disabled all mods, except for the "Alternate Start - Live Another Life" one, but to no avail. Regardless of the start point I select, it crashes immediately.

This may or may not be related, but when I first started the game at the part where you're riding on the horse carriage, the carts would start flying in the air. At one point my screen started constantly spinning in a circle and I had to restart the game.

thats a serious conflict then remove any meshes folder from ur game directory, delete ur ini files and then verify integrity of ur game files and check again
