preLaunch error on startup with some mods.

[FrostFizzie]

Version: 1.20.2.
Mod Version: 5.1.6.

Mods: Too lazy to list so here is a screenshot.

Issue:

Game crashes on startup with certain mods with error starting Could not execute entry points stage 'preLaunch'.
Going back to 5.1.5 does not crash but doesn't include the appleskin stuff. D:
It does not say all the mods the mixins are crashing with or whatever, but firstly it is with Capes mod to see capes from different mods, and then if I remove that it changes to Essentials.
