Server can't stop properly

[oxzin]

After installing the mod and then stopping the server, the server gets stuck at [Server thread/INFO]: Thread Query Listener stopped and never shuts down.

Server version: Fabric 1.21

Is that the only message it produces? There’s no errors in the log or anything?

I don’t believe I have any active optimizations that touch the Query feature. That means it must be something else that is stalling the server.

I
latest (1).log
couldn't find anything out of the ordinary, there were some errors but they were there and the server could be shut down completely, here is the log:

There is a decent chance that this error being thrown right here is the problem, though I cannot be for certain. Are you able to replicate this issue without potatoptimize? Also, I noticed the server is in offline mode. There is a chance that is the issue as I always test the mod in online mode.
