Hello, thank you for reaching out to Microsoft Q&A.
Based on your description, it seems that you've changed your Security Information in your Microsoft account.
According to the Microsoft article below, if you have removed all of your previous security information and replace it with something new, your account will be put into the restricted state for 30 days and Microsoft cannot expedite the process.
Reference:
security info change is still pending
If you don't want to wait 30 days, your only option is to do a clean installation of Windows 10 from a USB bootable installation media and use it to reinstall Windows. However, this process will delete all data stored on your HDD.
