Game won’t start and just freezes

I haven't played in about 2 months and now when i try open my game it just freezes and never opens. I deleted all the caches, repaired the game, ran app recovery and the only thing that could get my game to start is if i remove all mods. I tried adding them back little by little (i have about 6000!) but i only ended up adding a few 100 and then the game wouldn't start again. Are all my mods just outdated or something, all at the same time? Is there a way to fix this without adding them to the mods folder one at a time, because that's gonna take a while 🙈
