Describe the bug
carpet-fixes can't load the configuration file nor save to it, making applying changes permanently impossible.

To Reproduce
There are two ways to reproduce this behaviour, since this bug report is a combination of two possible paths to achieve it.

Steps to reproduce the behavior (via configuration file):

1. create a configuration file on world/carpet-fixes.conf
2. add any fix to it
3. open the server
4. type /carpet-fixes
5. see that the mod didn't load anything

Steps to reproduce the behavior (via in-game commands):

1. set any fix
2. once the mod asks you to set it permanently, click on the message and press enter
3. see the "an unexpected error has occured"

Expected behavior
carpet-fixes loads and saves to the per-world permanent settings.

Additional context
carpet-fixes didn't seem to load the per-world configuration file (which seemed to be located at world/carpet-fixes.conf) on my local test server, which prompted me to research if i could set those configurations permanently by hand, which would still be a bother but make carpet-fixes a part of the server-side modpack.

while trying to set the fixes permanently, the game returned that "An unexpected error occured trying to execute that command", and upon closer inspection that NPE (or most likely, a mixin error, cause there would be no way that this.server would be null while the mod has loaded).

"net.minecraft.server.MinecraftServer.method_27050(net.minecraft.class_5218)" seems to be the cause of that issue. i currently don't have any tooling configured but could help finding the cause of that bug once i have that setup.

I can confirm that this bug happens on clean quilt and fabric servers with only carpet and carpet-extras
