The old way of using managers to install mods was making the game unstable. You have to delete the game through Steam, then reinstall the game. After that Verify the game files through Steam. All mods are to be drag and drop into the games new Mod folder. Do not use managers as they just install mods right back into the game’s content files.
If you delete mods that you have used on a saved game file, then when you reload that saved game file, where is the game to get the model from? Of course it will crash without that if you delete it.
Just re-install the game and you should be good, just don’t use managers for mod installs. Game runs fine.
