It seems that the message you are encountering indicates that the service is not available in your region. Unfortunately, this is a limitation based on geographic availability, and there may not be a workaround if the service is not supported in your area. Since you have already tried restarting your PC, using a VPN, and clearing your browsing data without success, it may be best to check with Microsoft support or your local Microsoft representative for any updates regarding availability in your region.
