Did not work. I've tried everything.
The only solution for me was to factory reset Windows 11.

I delete the integrated webcam I checked mark to uninstall integrated webcam ......

How can i install it again

Thank you so much for making this video. It helped me to sort out my issue after so many days.

ALL YALL HAVE TO DO IS CHECK IF THE "Windows Camera Frame Server" service is enabled. THATS IT!

Hi I tried all the options in your video and it did not work for me. When I use Whatsapp desktop it happens.

Thanks, bro

Man I've been doing each step for the last 2 days and still cant get the damn camera to start. Sucks

Troubleshooting & resting camera app worked for me.. Thanks for the video!!

how to do this for windows 11

I have the same Problem with my Cellphone -_-

tks sir, my camera now is on. many thanks

didnt work, whenever i turn on the camera, it turns on for a second befdore turning off, been at this for 8 hours straight now

Thanks . I was able to get 2 cameras to be used -ONE AT A TIME - but not simultaneously and not displaying in the same or seperate windows. There are some apps that allow 3 cameras - but windows photo app is not one of them. Its one at a time. If you are still seeing that error. Try making sure the plug and play services are all working and that the second webcam is really working. The device manager needs plug and play. So add that to your list. and use a decent cable for the camera some of those that come with the web-cams are cheap.

Uninstalling and installing it again worked for me, Thanks

Uninstalling the camera on the device manager and scanning for hardware changes fixed my issue..

thank you very much

EVERYBODY! i have a potential solution if its your case. I bought the void elite headset from corsair and my camera wasn't working since i was using it. I have this same error but i didn't knew why. Here is how to fix. Make sure there is NO more then 2 microphone connected to your computer. If its not resolved yet if you have the same headset then close it, unplug the bluetooth usb 2.0, then replug it and turn it on. That's what i did and it work. The problem got fixed when i unplugged my old microphone.

None of these solutions worked for me

oh good lord, thank u sm

Just AMAZING! Thank you so much.

Thank you so much bro!!
You made my day. After a lot of struggles, after losing all the hope I decided to check on one last video and finally I got benefitted from that.
BTW deleting all temp, %temp%, prefetch worked for me.

I am very grateful for your help. Thank you very much!

Changing the camera privacy settings fixed it for me on my laptop. Had to switch the settings to allow apps to use camera. Cheers!

I just want to say THANK YOU!! I tried so many things to get my camera working again and your recommendation re uninstalling and updating drivers was the ticket. Thank you so much!

Thanks a lot brother 👍🏻
Uninstalling and reinstalling camera driver in device manager helped me resolve this issue..

The real solution to this problem is for Microsoft to permit multiple applications to be able to use the camera simultaneously instead of the exclusive nature of the operating system as it is now. Mac OS allows the camera to be used in multiple applications at the same time. This is a PC only issue. (This is not a PC vs Mac rant, just the facts). If enough people complain about this to Microsoft, nothing will happen anyway. They don't listen to their customers.

I LOVE YOU!! Fixed my cam right away--bless your days!

tysm! now my laptop camera working again! ty ty ╰(*´︶`*)╯
