Dell XPS 13 Plus webcam not working uder Linux

this has been posted before, but none of the solutions online did work for me (including this one from official dell support: https://www.dell.com/support/kbdoc/en-uk/000203830/webcam-is-not-detected-on-xps-13-plus-9320-laptops-running-ubuntu-22-04 )

Essentially the webcam used to work just fine (not with Cheese, but with all other software such as MS Teams and Zoom), but recently stopped and I am getting a bit desperate as none of the solutions seems to work and I don't know what to try next or what to do to better diagnose the problem.

Currently, I have Ubuntu 22.04.3 LTS installed, and the kernel is 6.2.0-33-generic.
