Android TabLayout can't be instanciated

I added a TabLayout to my view in android. In the Layout editor I get following notice:

java.lang.IllegalArgumentException: Motion easing theme attribute must be an @interpolator resource for ?attr/motionEasing*Interpolator attributes or a string for ?attr/motionEasing* attributes.

When I launch the application, it doesn't crash, but the TabItems, which I added with a TabLayoutMediator, are not visible.

What is the reason of this error?

My AppTheme inherits from Theme.Material3.Light.NoActionBar
