Dell XPS 13 Camera Issues 0xA00f4244

I am really mad & frustrated. I have been trying to resolve this problem since 2019. Do not try to suggest me, try this and try that. My driver isn't listed under Device Manager. When I try to install the driver through Add new legacy, Camera doesn't show any driver, Imaging devices only shows Microsoft, Canon, and Creative camera. None of them works. Now I have to work from home, my camera does not work. Can not join meetings or anything.

My camera has full access to the apps and is on. I have uninstalled the camera regular way and reinstalled it after restart. Does not work, Rolled back and installed again, does not work. I used registry edit (regiedit) to remove the device, restarted and installed again. DOES NOT WORK! 

I think this Camera thing is a total scam. My camera was working just fine, but as soon as my warranty expires, I see this camera problem. I can not use Skype, I can not do video calls on Facebook, I can't join meetings on Microsoft Teams. If I want to get it fixed I have to renew my warranty, which means spend more money. I bought this laptop in 2017 and this particular problem exists since 2012. Are you telling me you still do not have a valid  solution for this? If you do, why not fix it when you launched the new versions and why isn't the solution made public?
