an error was happened when im trying use coreprotect

[jbhkgkug]

I installed CoreProtect for my server to prevent it from being destroyed. But when I use the command "/co rollback <a player's name here> time:5m" (meaning restore everything the player has destroyed in the last 5 minutes) for 4 times, the destroyed thing is restored successfully, but the server's control table gives these error messages:

the server version is paper-1.21.1-52, and i installed jdk 22 to run it.

This appears to be an issue with CoreProtect. I'd recommend speaking to them about this issue.

I've built a v23 of coreprotect, currently using it in a 1.21.1 Paper server.
