Windows 10: I have a digital license on my Microsoft Account but windows can't activate with error code...

As the subject says, I have reinstalled windows 10 on my machine cause my windows crashed.
I have been reinstalling windows more than 10 times now in the previous years and my digital license worked great until now.

I have logged in my microsoft account just as the other times i have reinstalled windows 10 but this time it says that "Windows reported that no product key was found on your device. Error code: 0xC004F213


Please help.

Link Microsoft Account to Windows 10 Digital License


Hey, I have a question.
Do you think the digital license is saved on my MSA after i changed back to my local account?

What I mean by that:
I Added MSA to my Windows 10 and it said in Activation tab "Windows is activated with a digital license linked to your Microsoft account", and my PC was in device list of my MSA.
But I don't like the fact that I have to type in password every time I boot up. It's my private PC, I don't need password, I never had. So I switched back to my Local account. But now it's back to "Windows is activated with a digital license" only, and the PC is also gone from the device list on my MSA account.
Do you think it actually unlinked the license, or maybe because I logged in once, it saved anyway, and I will be good with activating in the future on a changed machine?
