Windows 10: Camera app not showing preview

The camera light doesn’t turn on when I open the camera app, so it just shows me a grey screen. No error message appears. But when I click the button to take a picture, it works. I just can’t see the preview. It very suddenly happened. My camera app was working fine just a few minutes ago, I’m not sure what happened. I did everything I could. I restarted my computer multiple times, made sure my camera was allowed access to the camera app, checked for updates, even uninstalled and reinstalled the camera app and my camera itself. Nothing helped. My camera works fine on other apps like Skype, Dis

download Windows camera app

Success in resetting Store; that produced a download of the Windows camera, despite seeing error message again, download proceeded. Screen shows MS app for Windows camera and indicates downloaded. (Camera now listed in app list.) But when Launch was selected,
no action after screen with camera icon. Eventually message appeared " something went wrong: here is message code if needed: 0x400F4271>MediaCaptureFailedEvent>0xC00D3704. We seem to be moving ahead a step at a time. Next suggestion?

 

Windows Camera App not showing under App Volume and Device Preferences

Hello, I have a Dell Inspiron 5502 running Windows 10 version 22H2. I have a sound issue. Under Settings>System>Sound >Advanced Sound Options>App volume and device preferences I have my system default sound input set to Virtual Cable, and I individually choose the input for other individual apps (Audacity, voice recorder etc). [[ See Picture ]] However, I want to set the input for the Windows Camera app (webcam) to "Microphone Array" (the built in laptop microphone), but the Camera App is NOT showing up in the list when I start the app. So I can't change the audio input for the webcam app unless I change the default setting for the whole system first. How do I change just the input preference for the camera app? Or how do I get the camera app to properly show up in the list of apps under: Thanks!!

- - - Updated - - - NEVER MIND, I just found it. Apparently, even thought the Windows Camera app is running, it will not show up in that list until you initiate a video recording. Then it appears. That is not the case, for example, with Windows voice recorder, which will appear in the list even though it's not recording anything. Stupid computer systems. lol. ok, it's me. Have a great day, week, year and life everyone!!!!!

 

Missing apps: Store, People, Photos, Games & Camera on upgrading to 10

Thanks for replying spunk. That's the 'alphabetical' list I was referring to, none of these apps are in that 'All apps' list. Any more suggestions?
