crash log as follows:
---- Minecraft Crash Report ----
// Don't do that.

The watchdog error happens when the server takes too long to process a tick. It doesn't look like your server is lagging though -- you don't have too many entities loaded. It seems more like there's a deadlock somewhere when reading a file, which could be a Minecraft bug.

I think your best bet is to try updating cloth config to 9.0.94 (https://www.curseforge.com/minecraft/mc-mods/cloth-config/files/4147099). I think 6.2.57 is meant for Minecraft 1.18 and there might be an incompatibility.

You can also try restarting the computer the server is running on. If that doesn't work, you can set max-tick-time in the server properties to -1 to disable the error, but then the server will likely just freeze indefinitely.

I'll be releasing a 1.19.4 version of this mod soon which you can try updating to if none of these work.
