Hey so modding can be a bit tricky with crashes and stuff, but i've found some pretty reliable ways to keep things running smooth. First off, its super important to grab your mods from places like nexus mods, i learned that the hard way after getting some sketchy ones before. Maybe interesting, running the game in directx 11 mode makes everything way more stable - just add -dx11 in steam, and youre good to go.

Always back up your saves before trying anything new, trust me on this one. When you're installing mods make sure to follow the instructions really carefully, especially when it comes to putting files in the right folders like win64. Something i've figured out is that its best to test one mod at a time, that way if something goes wrong you know exactly which one caused it.

If things start getting weird or crashy, try switching on high-performance mode in your gpu settings, it can help a lot with performance. And if you're still having trouble, just remove all the mods and add them back one by one, its a bit tedious but works like a charm. The community's pretty good about keeping mods updated too, so make sure you're running the latest versions of everything.
