Absolutely nothing provoking it. C2me existing for a bit is enough to crash the server. This is a server crash btw ;)

Try disabling the no tick view distance in the c2me config, some anti-x-ray implementations have problems with that option. Alternatively, you can also try a different anti x-ray option like the one from:
https://github.com/the-glitch-network/plymouth-fabric
This one has support for c2me's no tick implementation

how do you get to the config?

how do you get to the config?

It's in the config folder inside your .minecraft directory. The config file is called c2me.toml. You can open it with text editor.

It's also crashing for me. When will this be fixed?

Closing as antixray now have proper C2ME support.
