Need help with ACS system

I set up the ACS system correctly, but once I add a StarterCharacter to StarterPlayer, the ACS system stops working entirely. Is there a solution to this? Thanks

ACS is a complex system which is dependent on a lot of core parts of the avatar, if something within the character is named differently, for example, the left arm, then it can break the entire system.

Without further information such as console logs there’s no definite answer.
