Since my last firmware update, my integrated webcam (despite being detected) is showing a blackscreen. I tried with Zoom client, Google Meet and Slack huddle. Same behavior on all.
Cheese is not responding when I try to launch it (I don't know if it's related).
I also tried a webcam test on https://webcamtests.com/, it says that my webcam is detected but the test shows a blackscreen.
Yes, my webcam is enabled in my BIOS settings.
