You might have to check to see if any of those mods require a mod that's unchecked. Some mods require another to be active, otherwise it'll crash on startup. Do you use LOOT? LOOT will help greatly here.

What BandiKoot said, if you want to see what else might cause an error, get FNVEdit, the program runs all the active esps and esms and if there's an error it will tell you and tell you what esm is needed to run.

It could be some mods you had used or worked with stuff from Project Nevada, see if any versions of your mods use it, but that's just a guess, your best bet is to use LOOT or FNVEdit

Your problem could be clashing mods, wrong load order, missing masters and so on. What Bandikoot said, you can use LOOT. LOOT is a program which checks for load order errors and clashing mods, the program will sort them as good as possible.

You can also use FNVEdit, as AMOneEighty said, to see if you are missing masters for mods. To do this you must check all the mods who are active in your mod manager. It will then run all the mods one by one to see if there are any errors. When it stops loading while it isn't finished yet, look at the last mod. You will see it is missing a master and you need to add that in order for that mod to work and run it again.

Hope this post gives you some more info on what to do. For tutorials I'd like you to refer to the channel of Gopher .

Yeah he explained it better than me haha. It'll tell you a ESM is missing and if you check the list it will tell you what specific ESM it needs.

Definitely check out Gopher! He helped me out greatly when I first started modding my New Vegas and Skyrim! He's a go to guy for modding!
