minecraft-exported-logs-2023-01-22T22-50-22.log

when i using printer to build my building, it suddenly crashed, and i can`t join the game until i join another world to close the printer hot key.
this server is myself server so i can make sure server not ban anything.and pls allow me hide the IP and port. thanks.

It seems some file was broken because the name of the variable causing NPE was some strange characters.

I think this file is from Minecraft server JAR (not Fabric loader JAR).
