Built-in Camera not working with Microsoft Teams

Hi Jennifer
I am Vijay, an Independent Advisor. I am here to work with you on this problem.

Windows Key+i > Privacy > Camera > Make sure that Allow apps to access your Camera is ON
Also down below Choose apps that can use your camera is ON for Teams. If this is already ON, make it OFF and after few seconds, make it ON again.

Do let me know if you require any further help on this. Will be glad to help you.

Hello Jennifer,

I'm Independent Advisor and Microsoft MVP, here to help you with your question.

Please refer following suggestions:

Run Hardware and Devices troubleshooter from Settings app > Update & security > Troubleshoot.

If that doesn't helps, try to re-register Camera app:

1. Press Windows +X and select Windows PowerShell (Admin).

2. Type/paste following and press Enter key:

Get-AppxPackage -allusers Microsoft.WindowsCamera | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

3. Close Windows PowerShell and see if this resolves the issue.

Otherwise, try these steps:

1. Press Windows + X, select Device Manager.

2. Under Imaging devices, right click on your camera device and select Uninstall. Click OK.

3. Then click Action > Scan for hardware changes.

4. Close Device Manager and reboot.

Let us know if this helps!
