Before Continuing:

• Always check you are using the latest version of the mods and its dependencies
• Remove mod that enhances Minecraft: Optifine, Sodium, others. The issue still persists.
• If you are unsure which mod is the culprit.
  Disable all of your mods and enable them 1-2 mods each time to isolate the culprit
• Confirm that there is no existing issue with a similar description submitted in the list of issues.

Version

1.21.1

Loader

Neoforge

EveryCompat Version

EveryCompat 1.21-2.7.2

Moonlight Lib Version

Moonlight - 1.21-2.15.2

Issue with mods

Not an issue with other mods per se, but an issue with loading the config before it was generated.

Issue Detail

I cannot boot up the latest version of 1.21.1 with Every Compat, I haven't tried without any other mods, but this mod is the issue since I can launch the game without it.

OPTIONAL: Latest.log | Crash-report Attachment

https://mclo.gs/GXevCvv (With full mod list, including performance boosters.)

https://mclo.gs/3v2Ne45 (With performance boosters removed)

OPTIONAL: To Produce

Place Every Compat into the mod folder.
Launch game.
Crash.

Can you run with the following:

• EveryComp
• Moonlight Lib
• Supported mods (choose one)
• Wood mods of your choice (Can be biomes O' plenty or others)

Launch the minecraft. If you have no problem, then add 1 or 2 mods until you got the crash. then isolate 1 of 2 mods to see if you can reproduce the crash with just one mod

I will try it out. Thank you for the response!

Ok, after a painstaking couple of launches, I have found the culprit to be Colossal Chests. I will report this to the development team for that mod. Thank you again!

I see. Colossal Chests isn't supported by EveryCompat. Good idea to report it to team.

You're welcome.
