I just updated my Dell XPS 15 9570 on Windows 11. Now the integrated webcam is not working anymore.

It is not displayed in the device manager. It is also not found if I search manually for new hardware in the device manger. Further I checked the troubleshooting with Dell Support Assist, but also there no webcam is found. I also ensured, that the Webcam is activated in the BIOS.

Does anybody know, how to solve this issue? Is there a way to manually install the necessary driver?
