    Also having a similar issue in 2021.1.0f1.

    I get these two messages and it recreates the components I keep deleting on my PlayerPrefab.

    Creating missing CapsuleCollider component for PlayerController in Player_Prefab.
    Creating missing Rigidbody component for PlayerController in Player_Prefab.

    I delete and things work fine. Then a while later when working on the prefab those warnings pop back up and it recreates those components.
