Windows 10: Windows Defender stuck off

Hi Everyone,

Recently my windows defender was unexpectedly turned off. On the panel it says "Threat service has stopped, Restart it now." With a restart button below. When pressed it simply loads for a while, and then an error message occurs image attached.


I would really appreciate it if anyone has had a similar experience and/or knows how to fix it!


Thanks!

:)
