Sprite Editor does not open for me in Unity 2022.3

I followed the Learn Unity Pathway for Unity Essentials. Everything worked as described. I’m now stuck in the 2D tutorial. I was able to do everything 2D releated until the step to add an animated sprite. When clicking the “Sprite Editor” button in the inspector, nothing happens. Neither does anything happen when using the menu entry “Window → 2D → Sprite Editor” or “Windows → Panels → 7 Sprite Edittor”.

The 2D package is installed. Otherwise I wouldn’t have been able to follow the 2D tutorial until this step.

There are a few results I can find in the internet about this issue, but they have been reported long time ago and happened on pretty old Unity versions. Is there any Unity log file which can provide me more hints at what is going wrong? There are no entries in the console window, when I am try to open the Sprite Editor.

Unity version is current 2022.3.34f1.

Oh dear, the Sprite Editor did open, but it opened on my second monitor which was switched off so I did not see it. No clue why Unity opens anything on the second monitor. Unity runs in maximized mode on my main monitor.
