I fixed it by completely deleting the game and all the shit I put there and going through the guide on vivanewvegas.
It now works smoothly and I get no crashes. Everything works perfectly which kind of surprises me. I added a few more mods besides the "base" that are just small and won't affect that much and I'm having fun.
Stutter remover caused me crashes in the past because it's apparently not supported well on windows8/10/11, only on 7.
