HI Jason!
I see that you have the wonderful surface pro 6 which you can update the firmware using this link,
https://www.microsoft.com/en-us/download/details.aspx?id=57514.
Kindly restart after the install is over and check if the camera is working.
If it's not working I suggest contacting via chat to the Surface technical team that will help you with your issue as they have always been so nice to fix all my surface issues.
Support.microsoft.com/contactus, make sure you are signed in, type talk to agent, press next then choose Surface, Hardware, Surface Pro. Press chat.
If all fails, I recommend doing a surface firmware recovery as that will completely wipe the computer and reset all the drivers. It's not the same as reinstalling Windows 10 as this may fix up the other issues.
https://support.microsoft.com/en-us/surface/creating-and-using-a-usb-recovery-drive-for-surface-6778...https://support.microsoft.com/en-us/surface-recovery-imageThe first of the two links will provide you details on how to setup the USB then you may download the recovery media from the last one.
Please make sure you follow all the steps properly, also if you are with a agent, they will be able to help you also through this over the phone.
If all else fails, it could be a hardware issue which has to do a replacement which they can help you with if you have warranty or other options.
Hope that helps :)
God bless and have a wonderful day!
Shawn - Surface Pro 5
