Minecraft crashed and I don't know what is causing or if its a mod?!

[GitHubUser0220Yu]

I was playing a modpack I made using cobblemon and various other mods, and it was working since 3/5/26, and then it started not working,g with getting issues saying things like it's due to a mod or two, which I was able to fix. Now

I am getting a different message. Here is an image that shows the message I am getting when trying to create a new world.

Any way to fix this issue? It would be a pain to check every mod to see what's causing this issue just because of this. :(
