Hello,

Are you currently on Windows 11 Home and you got the Pro from App Store?

If so, You can go to Settings > System > Activation > Change product key

Disconnect internet, and disable any third party antivirus, key in the generic key instead: VK7JG-NPHTM-C97JM-9MPGT-3V66T

That should get you to Pro. Once restarted, you can connect back to the internet, sign into your Microsoft account. See if it is activated.
