Dear , Ryan Murphyhbm Welcome to Microsoft Community.That sounds incredibly frustrating, especially when everything worked smoothly before.There's no need to worry; I'm here to assist, and we can work together to resolve this issue effectively. Here are some steps you can try to resolve your issue.
Force Exit Safe Mode: First turn off your P.C. completely. After that try to on it by holding the power button. Repeat it three times and on the fourth boot your PC will enter the Windows Recovery Environment (WinRE). Go to Troubleshoot > Advanced Options > Startup Settings > Restart and choose normal boot.
Reset PIN or Password: Reset your password using Microsoft password reset page and try to login again with new password.
Boot Using Recovery USB: You can also resolve this issue by doing the Boot using recovery USB
Last Known Good Configuration If your PC doesn't offer this option, boot into BIOS/UEFI and check for a setting related to "Last Known Good Configuration." Enable it and restart.
