server crash with /checkban

[Kbryst]

All I did was run /checkban . I did type /checkban (playername) after but it looks like the server had already stopped responding with the /checkban command.

This is the CMI version before the sell hand version. 7.3.11.0. Paper 1.12.2.

Does this still occur on the latest 7.3.13.0 build?

Not directly related to ban command as this one failed when trying to get offline player from Mojang servers with official API. Will try to come up with something to avoid this, but cant really promise anything at this point.
