Additional context
I am very sorry if this error is related to another mod. I would be very happy to provide any more info if necessary. I am not very good at reading the error logs, but i hope you have the patience and dedication to help me out anyway. Thank you very much.
I love the mod, because as of now it is the ONLY way to get dynamic lights in neoforge 21.0.x

For some reason, ryoamiclights.toml is written with the same paragraph twice. This caused some kind of problem reading the config file.

Reproducible in NeoForge 21.0.114-beta using only RyoamicLights and ObsidianUI. The paragraph only appears once when entering the game, and a second one will appear after entering a world. So if using the latest version of NeoForge and mods, the first time you enter a world it will not crash, but the second time you launch the game it will crash.

Maybe it is because of some breaking changes in NeoForge? I thought I would test it out.

It can be confirmed that this is caused by a breaking change in NeoForge. The problem started to occur starting with NeoForge 21.0.82-beta.

It's still broken even after update v0.2.10, the buggy config that @3gf8jv4dv mention is still being created even on NeoForge v21.0.167, which results in the game crashing after you relaunch it.
