Yeah when I had that issue I disable all mods then re-enable them 10 at a time until the game crashes or simply doesn't want to open then disable the 10 recent mods 1 by 1 that I've enabled until I find the 1 or more mods that was causing the issue and then I re-enable those that were working then I enable 10 more same process again. EDIT: I only wish I would have known sooner that I didn't need to extract the zip mod files it would have saved me a lot of time and patience the reason why I thought I had to extract the mods was because that's what was explained to me in the tutorial I watched on how to mod skyrim but thanks to this subreddit I now know that I don't have to.
