Mods can be troublesome because they are independent creations. You are definitely having problems with mod conflict so what recommend ou to do is unsub to all mods you have subbed and test what combination of mods work and what doesn't
Unfortunately there is no other way to know what mods combination are safe to use so you'll have to test it out by yourself

Mods that don't work and play well with each other are frequently trying to do effectively the same thing at the same time, like trying to wear two hats at once. I'm not necessarily suggesting the problem you're experiencing is something that obvious, it may be vastly more subtle like altering a background setting, like the combat AI or the decision tree for the animations.

What's even more infuriating, is it may not even be two (or more) conflicting mods, it's very easily possible it was a bugfix/update that the devs put out that "fixed" a problem the mods were deliberately exploiting.

Exactly as Random eGirl said: you're gonna have to go through, carefully, and find the mod that's causing you trouble the hard way... one at a time. Yes, it's a pain in the tuchus, but you'll not be alone-- we've all been there in one game or another. Think of it as a kind of bonus meta-game with no guides and no soundtrack for the boss fight. ^_^

Sure enough, it seems to be a mod problem. After I unsubscribed some mods, I can enter the game. Thank you!

Unfortunately the game can have problems launching when too much mods subscribed at the same time.

Thanks for reminding, I got it.
