After update to Unity 2022: Click into input field fails

I just upgraded Unity from 2021 to 2022 and noticed that the input fields are not working anymore, neither in the Editor nor on a mobile build.

I have enabled both input systems, and I have replaced the old input module with “Input System UI Input Module”. But with no luck.

If I tap on an input field on iOS like 20x, sometimes the cursor appears. But more often than not, the fields are just dead.

What might be wrong here?

Update: I just realized that the input fields gain focus, if I tap slightly above the upper border. But not if I tap into them or on the border itself. This is very strange.

Ok. It seems to be caused by an image that shows an input field border and which was placed above the input field itself. This did work up to Unity 2021, but not in Unity 2022.
