I'm running ferritecore-4.2.2 on the DawnCraft modpack on Forge 1.18.2-40.2.9 dedicated server (Ubuntu 22.10). On load start, everything was ok, same on the second start, then I played a while with my friends. On the third server start, it crashed without leaving any log or crash report.
Fixed the issue by running the starting script with root privilege access, everything is up and running again. However, I think this resembles a big security risk.

Here is the error I got from the output:

[17:51:05] [main/WARN] [mixin/]: Method overwrite conflict for m_47505_ in modernfix-common.mixins.json:perf.remove_biome_temperature_cache.BiomeMixin, previously written by com.abdelaziz.saturn.mixin.world.temperature_cache.BiomeMixin. Skipping method.

Please check the file permissions on the FerriteCore config in config/ferritecore-mixin.toml. The user running the server has to have write permissions to this file. If that is not the issue, please upload a full server log to https://gist.github.com and post the link here.

Running the server as root should never be necessary.
