CEM's first-launch crash

[Madis0]

Describe the bug

Sometimes there is a crash on the first launch, never on the second. I assume it is because some mod doesn't like YOSBR, but the exact cause is currently unknown.

Modpack version

4.3.3

Launcher

CurseForge Launcher

Other things

• I updated FO to a newer version (mention, what version to what version)
• I added/removed some mods or resource packs (mention, which ones)

ARRP is included in Enhanced Block Entities, so that's likely the mod in question...does it use YOSBR right now?

[Madis0]

No, FO does not provide a config for that mod.

This seems like Fabric Loader itself, I have problems with this bug myself that seem to be random. If it crashes like this, I have a 50% chance it will work on next launch attempt.

Interesting. I doubt it is reproducible with 0 mods or only fapi though.

It was suggested that this could be fixed by explicitly including CompleteConfig, but that didn't fix it for me: https://mclo.gs/9TXelmZ

Maybe 1.19.3 will fix it.

I think it is already resolved as of 4.6.0-alpha.6 (which is where CEM updated).

In 1.19.3 there actually seems to be a different error but a similar cause and workaround. Reported as dorianpb/cem#106
