Windows 10: Windows unexpectedly deactivated after a BIOS update

Hello. Yesterday I did a BIOS update on a B760M Gaming X DDR4 from F18b to F18d containing the 0x129 microcode. After that, Windows 11 Pro deactivated itself, even though worked well the day before. It shows an error code: 0xC004C003. In the activate by phone method they told me that the key is not valid so they couldn't do anything and I had to purchase another activation key. Why? How to fix it? If the key really is not valid, why did it work flawlessly throughout a whole year?

Should I update bios?

I would read the warranty before doing anything. If the manufacturer finds out you did something not on their approved list of steps,for example using a program they didn't list, or a bios, etc, they can treat your video card rma like you threw it against the wall , because if something goes wrong and you didn't follow their steps exactly ,it was damaged through human error and they're not likely going to be obligated to cover it warranty wise. I don't know for sure, I just advocate that you check first , and I also advocate that you verify that it's an actual update ,because very rarely do manufacturers release updates for gpu bios'. And they most certainly wont cover a GPU "update" if its a bios file written by some dude in the Ukraine, it has to be a set process, they have predetermined often.
