SOLVED by @fatedust HERE:

The last time (7D91vH4), I could easily reactivated using the digital license, but now I can no longer do that. I know calling Microsoft might help, but is there any more convenient way?
Hint: I updated BIOS for multiple times (7D91vH2 -> 7D91vH3 -> 7D91vH2 -> 7D91vH4 -> 7D91vH5).
The error message: "We can't activate your copy of Windows as the digital license for this device has already been used to reactivate Windows"
