Hello ChristyTaylor1
I'm peter F
Please follow these steps
Open the Store app, search for Windows Camera app and then install the same.
If that didn't work
Note : be careful with these steps
Step 1: Run Windows PowerShell as administrator. To do so, right-click on the Start button on the taskbar and then click Windows PowerShell (Admin) option. Alternatively, type PowerShell in Start/taskbar search field, right-click on Windows PowerShell entry and then click Run as administrator option.
Step 2: At the PowerShell window, copy and paste the following command. Press Enter key to execute the command.
Get-AppxPackage –AllUsers
Step 3: Now, look for Microsoft.WindowsCamera entry. Select the PackageFullName of Camera app and use Ctrl + C hotkey to copy it to the clipboard.
Step 4: Execute the following command to uninstall the Camera app.
Remove-AppxPackage PackageFullName
In the above command, replace PackageFullName with the actual PackageFullName that you copied in the previous step.
You may close the PowerShell window now.
Finally, open the Store app, search for Windows Camera app and then install the same.
I hope it helps
