Kindle Scribe not showing up as connected in Calibre

Hi

I have problems connecting my Kindle Scribe to Calibre. When I connect my Kindle to my Windows 11 notebook, I hear that it is recognized, but it doesn't show up in Calibre. I tried different cables, different ports and changed the power settings for my USB, but nothing solved the problem. I can connect the scribe to calibre on another computer, so Scribe and the cable are not the problem.
Any help would be appreciated!
