Can't add TrackedTransformAuthoring to MovingPlatform prefab

Unity 2022.3.7f1
com.unity.charactercontroller v1.0.0-exp.22
com.unity.netcode v1.0.15

As you can see in the screenshot. TrackedTransformAuthoring is exists. But Unity can’t find it for some reasons. Can someone help me?

Are there any errors in the console? First they would have to be fixed.

If that still doesn’t work, try closing unity, deleting Library folder, and reopening unity. Look out for any errors once you reopen

After deleting the Library folder. Now it works. Thank you.
