The game crashed whilst unexpected error Error: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered

Minecraft Forge 1.19.2 (43.2.14)

(1) Please note that there is no SpongeForge for 1.19.2. Mixins are something a lot of other mods use, and SpongePowered has no control in how they use them. It’s best to seek help from the mod developer.
(2) The cause appears to involve blue_skies.mixins.

Could you tell me which mod is giving the error?

Inscrutable does. He said its blue_skies.mixin. if you dont have a mod called blue skies then you could use a program like Mixin Detector to work out which mod holds that file
