Hi. I'm David, and I'm happy to help you.
To be able to assist you better, please clarify the following:
- Do you use the native Windows "Phone Link" feature or a third-party app? If you use a third-party one, which one?
- Is your phone currently connected to the computer via USB cable or via Wi-Fi/Bluetooth?
- Are you testing directly in a browser or using a dedicated app? Please specify which one.
- If you open the native Windows Camera app right now, does your built-in webcam display an image or show an error?
Looking forward to your reply.
