I'm sorry to hear you're having this problem, and I hope I can assist you to find a satisfactory solution.
To get a better understanding of the issue and provide a resolution suitable to your concern, kindly provide the following information:
Do you use a VPN or any browser that have built in VPN on it?
Have you Installed any extensions?
Have you made any changes to your device prior to the issue?
This could happen after too many failed attempts; Microsoft is definitely restricting your IP address or device (or both). You must utilize a totally different device, such as a phone or laptop.
