Character's trigger collides with itself

I attached a capsule trigger to the standard Unity third-person character controller, and now the OnTriggerEnter function runs when the game starts, but doesn’t run when the trigger collides with other objects. I think the issue is that the trigger is constantly colliding with the character controller. Anyone know how to fix this?

Try this: attach a rigidbody to other objects.

That was it–thank you!
