Bug Problem with Interrupted Transition

Hello,
I have a problem with my humanoid rig typed character since Unity 2022.2.

I have transitions in my animator that can be interrupted by Interruption source="Next State".

This works since 2022.2 but only as long as you don't add any more layers.

To double check I opened the "Starter Assets - Third Person Character Controller" with 2022.2 in a new project.

To reproduce the bug i added a state to the animator that plays the run animation.
The transitions are both Interruption source = "Next State".
Additionally I added an empty layer (which triggers the problem)

Now you can see that the char sometimes flickers or gets under the ground.
