    If you have another antivirus installed it might turn OFF Windows Defender, please validate what you have installed.

    If you have no other antivirus, please check your event log for further information on the why it closed.

    I'd check the system event log for error details about this service.

    If you installed other third-party security/antivirus software, Windows Defender will disable itself automatically, you need to check this point.

    On the Microsoft Community there is a related post about that, that show you can try to troubleshoot this problem. Just try one after the other.

    Restart your PC

    Remove existing antivirus and antispyware software

    Scan your PC for malwares

    SFC scan

    Clean Boot
