i used /player SweaterOMG (my name) interval 11 and now i cannot get myself to stop attacking in game no matter if i close out the whole launcher or not
tried using /player SweaterOMG stop does not work either

I don't think that would be possible.

Closing this as there's been no feedback in a while. If it's still an issue, feel free to comment and it can be reopened, or make a new issue.

I have the same problem on a 1.19.3 server and it also does this in my singleplayer worlds.
Have you fixed the issue?
Pls let me know

Do you have a way to reproduce it with just Carpet? Or could you find a minimal installation.

Please give the exact steps, it'd be very helpful.

I haven't been able to reproduce this, and it's very strange because Carpet doesn't save actions afaik, so they're always reset when reloading.

It fixed itself after restarting my pc and I could not reproduce the problem too. The game crashed while on the server and after restarting the game it still was a problem but it could be that something had hung up in my own files.
