Windows 10: My computer won't let me reset my pin

Recently I signed into my school account in Microsoft Edge so I could do my homework more conveniently and the next time I tried to sign into my computer it popped up with a message saying "Your organization requires that you change your PIN" when I tried to use letters it didn't let me, so I just made a random pin and wrote it down. When I tried to go into settings to change my pin back to what it was it said "Something went wrong. Try again later." and now I am unsure of what to do. I am currently on a personal computer with my personal Microsoft account running Windows eleven home
