Webcam will not track motion in Character Animator

Hi,

I'm very new to Adobe CH, and for some reason it won't detect head or body movements from my webcam. This is not an issue with puppets or their setup, because I've used lots of different Adobe pro puppets to test, and none of them work.

I've had 2 different sessions with Adobe technical support, where they've remote-accessed my computer, and neither were able to find a solution. I've bought an external webcam today, and its the exact same issue. My webcam connects, I can see myself, the audio and lip-sync works fine, but no tracking lines appear on my face, and no response from the puppets (adobe tech support did the same, and also couldn't get it to work). I've tried lots of different positions for me and webcam, also tried maximising lighting, I've disabled all other software from accessing my webcam, I've changed webcam settings, I've uninstalled and reinstalled CH multiple times (and installed previous versions), I've updated windows, graphics card drivers, webcam drivers. Nothing works. I've trawled online to find solutions, but nobody else seems to have the same issue as me.

I'm using a 6-month-old laptop (Windows 11), Asus Zenbook i7 (16gb).

I'm really lost, would really appreciate any help!

Thanks
