Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.
I understand the issue you have, there is nothing to worry I am here to help, better if you can purchase directly through the Microsoft website: https://www.microsoft.com/en-us/d/windows-11-pr...
As that is only a legal and genuine product, third-party websites are not recommended as they might be not genuine and may deactivate and harm your device.

Let me know how it goes and I hope that helps.
