I think that this error may be common but it's on 1.19.4.

 

Firstly,I'm not an English speaker.So this article may not be very fluent.

I opened my Minecraft 1.19.4 Server with Fabric Mod Loader 0.15.6 as usual.But it crashed unexpectedly but I could open it normally last time and I did nothing to the files of the server between last time and this time that I opened it.I tried it on Windows and MacOS with Java 19 and was been returned the same result.I tried running the server without Fabric Mod Loader or without any mods but it didn't work,either.Then I supposed that maybe there is something wrong with the datapack I created,but I proved that nothing wrong with it.

And at first the exception is not that below but another strange one and the server.properties had become a mess:with a line of garbled codes look like unicode before the actual content and the motd and the level name had been replaced from unicodes I wrote with another phrase of unicodes and it was the characters just like "åß∂å∂∑œ∂ç≈Ωπ"(Add:not only this,but  almost every json file of the server had turned into garbled codes).Then I fixed it:I replaced the server.properties with a copy of that I created before.And I found one more problem:level.dat and level.dat_old of the save had been broken and it caused another exception.But I fixed it through the same way.And the next exception is below.Totally I met about three different crashing.

By the way,the save works well on client.

 

The server logs is below(On MacOS):
