Hi, I'm John!
Since this is a school account, it is likely a work or school Microsoft account managed by your school's IT department.
If you no longer have access to the phone that was set up for MFA, the account recovery form usually will not work because it is intended for personal Microsoft accounts.
The school's Microsoft 365 or Entra administrator will typically need to reset your MFA methods so you can register a new device and sign in again.
Have you contacted your school's IT help desk or Microsoft 365 administrator yet?
