[CRITICAL] Mutator Devices do not disable at all since v28.10 Update (Rendering any game that disallows player movement broken)

Anyone looking for a solution that isn’t ideal can use this.
Setup a third person control device
Configure movement in third person device
Setup a volume device
Connect the two with events
You can successfully disable the third person control device

However, your controls will be ruined using this method since third person camera control use is intended to be used with the new camera devices.
