v1.5.1 Forge 1.20.1
When trying to scroll to the next page with mods tabs in the creative menu, it causes a crash. Disabling the mod fixes the issue.
There is no crash on mod version 1.5.0.

You have too many mods installed. Try to reproduce this issue with max. 4 other mods installed

It looks like it was just a random crash. I have tried several times to reproduce the crash with the same mods, but without success.
If I encounter this again, I will reopen the issue.
