Mixin apply failed — fix a mod incompatibility
Example error line
Mixin apply for mod cobblemon failed
A mod tries to modify game code via a 'mixin' but can't find its target — usually a version incompatibility with another mod or your Minecraft version. The affected mod feature may not work correctly.
Check via the mods UI whether the affected mod has a build matching your modpack/Minecraft version and update it. If it persists, remove the mod or report it to its author.
