Windows 10: Windows 11 key suddenly deactivated. What do I do?

I recently updated my pc because it got a windows update.And right after it finished I got the "Activate Windows" in the bottom right of my screen.Which is strange because I've never had any problems since I've gotten my PC. Which was in JULY 2024.It gave me the error-code: 0xC004F213 - Windows reported that no product key was found on your device.My PC was prebuilt + preinstalled.I've tried to return to the previous update. when it was still working.I've tried factory resetting.I've also tried to fix it with troubleshooting.I've looked for a sticker on my pc with a windows activation key,

Windows suddenly deactivated, claims Pro key is Home key

Hi

After using my Windows 10 Pro install for about 18 month, my copy of Windows has suddenly deactivated, error code 0xC004F034. The exact error when using the troubleshoot feature is that the key is for 10 Home, not 10 Pro. However, this key is definitely
for a Pro installation, and it as mentioned, was working fine for at least 18 month before it has now suddenly deactivated.

Any one have any ideas how to resolve this?

Cheers!

 

Windows 10 pro deactivated suddenly

Windows 10 pro deactivated suddenly. I also tried reinstalling windows for 3 times. It was not solved in any cases. I brought a genuine key in 2022 ending. It is showing that you don't have vaild license please tell me what to do. Do I need to buy a new product key, if so I will buy a windows 11 key. I am depressed about it.
