Help me please, because i'm very love LuckPerms

Try updating your version of LuckPerms, you're running quite a few versions behind.

Grab latest builds from here: https://luckperms.github.io/

Also the error message does not in the slightest indicate an issue with LP.
Looks much more like an issue with Paper. Try updating Paper too. If it persists, report it to them.

In order to see what happened, we'd need to see the full log; But, nothing there indicates LP is at fault

Wow ! Oh Thk
