Hello,

What do you mean by inputting the Win11 Pro key in error?

Is this key purchased from Microsoft, or from third party?

Phone activation doesn't work anymore actually, you will likely need to contact support. But if I have a better understanding of the context, maybe I can help you here before we determine if contcting support is needed.
