Additional context

Try reproduce without C2ME.

Even if it happens, do you know which mod could be causing it and if it is a critical bug that affects performance or chunk loading?

It is probably some mod or datapacks are shipping a malformed function called watching:check. You'll have to check it manually

thank you
