Hello
Can you please go to Windows settings > Apps > Installed Apps? Find Camera, then click on the three dots, and uninstall it.
Restart the computer. Go to Store app, install Camera app back. See if that helps.
If it still gives you the same issue, Please type regedit in the search on the taskbar to launch registry editor, and go to this path, then take a screenshot and share in your reply.
