Webcam on dell XPS 13 not working

I am running Ubuntu 22.04.4 on a dell XPS 13 9315 and suddenly started having issues with my webcam.

The camera does not seem to turn on and just shows black in each application I try (chrome, cheese, kamoso, zoom). Previously, when the camera was wokring, the light next to it would come on. Now the light never comes on.

v4l2-ctl recognized Intel MIPI Camera as well as some ipu6 devices:

sudo v4l2-ctl --list-devices[sudo] password for benc: ipu6 (PCI:pci:pci0000:00):    /dev/video1    /dev/video2    /dev/video3    /dev/video4    /dev/video5    /dev/video6    /dev/video7    /dev/video8ipu6 (pci:pci0000:00):    /dev/media0Intel MIPI Camera (platform:v4l2loopback-000):    /dev/video0

The output of lsusb does not seem to recognize the camera:

Following other answers, I made sure that libcamhal-ipu6ep0 is installed properly. This did not seem to make any difference.
