hi,
You and I are on the same boat. I was doing an offline scan and it went to the recovery mode. I am assuming that this is normal. Yet, according to AI: When a Windows Defender Offline scan boots straight into recovery mode (or Automatic Repair), it usually happens because the Windows Recovery Environment (WinRE) partition is corrupted, the boot configuration data (BCD) is damaged, or BitLocker is blocking the safe handoff to the offline scanning mini-OS.
