I recently got this error in my unity project.

I can’t check in my changes and for some reason i can’t delete my prefabs in my project assets. I asked chatGPT for help, i should look for a “PendingChangeCategory class” but i can’t find it anywhere. I also tried everything i could find online. But nothing worked. I’ve been trying to solve this problem for 2 days and it’s driving me crazy!

Can someone help me please?
