Thanks for posting your query to Microsoft forum. I will certainly help you with this.

I would suggest you to start the computer with hidden admin.



Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. This helps us in identifying whether the issue is due to some third party
programs conflict. The word Safe mode appear in the concern of your monitor to identify which windows mode you are using.

Step 1: Safe mode

• Click Update and recovery, and then tap or
  click Recovery.
• Under Advanced startup, tap or click Restart now.
• Once your PC restarts, on the Choose an option screen, tap or click
  Troubleshoot.
• If you don't see the Startup Settings option, tap or click advanced options.
• Tap or click Startup Settings.
• Tap or click Restart.
• On the Startup Settings screen, choose the Safe Mode.
• Sign in to your PC with a user account that has administrator rights.

Step 2: Active hidden admin account

• Press Windows + R key on the keyboard.
• Type cmd in the run bar.
• In Command Prompt type this command: net user administrator /active:yes
• Press Enter and Restart the computer.

Try to create new user account now.

If you are able to do so deactivate the hidden admin account.

For that follow the step :
