Windows 10: Windows 11 suddenly deactivated

I have had this system for around 7-8 months with a genuine license. But today when I was minding my own business, a notification popped out of nowhere claiming that my windows was not reactivated.I tried various methods such as restarting the PC and troubleshooting the issue but they didn't seem to work. I also tried entering the product key in the settings tab but that didn't work either.The weirdest part about this is that the product key and ID are still showing up in the windows activation menu in settings.Also, a similar issue happened to my in my previous system which had windows 10 but

windows 11 deactivated suddenly

My windows 11 pro is deactivated suddenly and I am having trouble using apps on my pc. when i bought the device it had windows 10 running on it and it worked fine. This device came to me as a second hand product through a third party so I don't have any box or license attached with it. after buying the pc i moved to windows 11 from windows 10.At first I used to get notifications of "your windows license will expire soon, activate the windows" although the system always showed the active status whenever I checked, to get rid of this notification I followed a tutorial from internet here is the link for that "" but it didn't worked and now after one or two months later my windows got deactivated and when I activate or troubleshoot it shows error. I am mentioning the error code here "0xC004F074".
