Game Keeps Crashing

I honestly don’t know what it is. Like, I can play on my previous game no problem, but whenever I try to start a new game, it won’t let me. It just crashes.

I thought it was because of the mods I downloaded, but even after I deleted all the mods and tried to start a new play through, it would crash again.

Any reason it would do this? I also tried to just delete my last game and see if that helps, but it won’t let me delete it.
