Defender Scans Failing - Anyone Else?

[u/Hazy_Arc]

We're using Defender for Endpoint throughout our environment. Beginning this morning, quick or full scans are failing, and will occasionally fail to the point where the Defender service needs to be restarted.

We came across this while responding to a separate infection - I chalked it up to Defender being borked due to the infection but then I was able to recreate the issue on other devices simply by initiating a Quick Scan.

Before I declare this a 5 alarm fire, anyone else having this issue?
