Focused Shockwave failing to trigger, animation is stuck, MissingFieldExcepion errors in console/LogOutput

[TheTimeFace]

When "Focused Shockwave" is used, most of mobility is lost, the character jitters as if stuck in trying to play the animation. While that happens, the LogOutput.log starts filling up with the following:

[Error : Unity Log] MissingFieldException: Field not found: int RoR2.CharacterModel.invisibilityCount Due to: Could not find field in class
