isTrigger collider interfering with FirstPersonController

So, I made an isTrigger collider a child of any object I attached a specific script to in order to detect collisions on that object while still retaining the Rigidbody functionality of the object. The problem is that whenever my character runs over to the object, it gets stuck near the edge of the bounding sphere of the isTrigger collider and after a while of trying to get out of the collider’s edge, it finally lets me leave.

As far as I know, an isTrigger collider isn’t supposed to interfere or interact with the Rigidbody of another object, so why is this happening and how can I fix it?

You’re right, there is no way an isTrigger collider can collide with a rigidbody. There must be some other collider, maybe of some parent object or just something you forgot to also set to isTrigger or remove. Check all components for leftover colliders and if you can’t find any problem, create a test scenario. New scene with just the two objects that were causing problems. Then it should be easier to find the mistake.
