Hello!
I decided to install your mod in my assembly and now the client crashes the game.
Crash log attached.
Thank you!

crash-2022-11-12_12.05.43-client.txt

MixinBooter and MixinBootstrap are not the same thing.

In the crash log file, the line "33", in which this mod is indicated:
"java.lang.IllegalAccessError: tried to access class org.spongepowered.asm.mixin.transformer.MixinProcessor from class net.minecraftforge.fml.common.Loader"

Wow!!!!

There are several mods which provide slightly different implementations of Mixin. Please install MixinBooter and see if the issue persists.

There are no problems with this: it was installed automatically immediately after the main mod. It's in the mod list.

Hmm, it doesn't seem to be listed in the mod list in your crash report. Are you sure?

It had to be installed separately. I'm going to try now.

It seems like the game is loading without crash.
1 question: do these 3 mods need to be installed on the server or are they exclusively for the client?

They should be installed on both the server and client.

OK I understood.

So, the client has loaded, everything is fine.
I'll try to play, if anything - let me know.

I was inattentive to the crash information: I read the first half of the mod's name, but didn't look at the second half. I sincerely apologize for wasting your time!

No problem; glad you got it fixed. 🙂

Try installing MixinBooter as well.
