Defender is causing high CPU load

On several sites (all hosted on the same cloud) Defender is causing high CPU load. During file scan it becomes unresponsive and the wp-admin content becomes unavailable (that means that while back-end loads, pages in back-end are just blank). Recently, it couldn't even be reinstalled (loading wheel spinning indefinitely) and had to be manually removed via FTP first.

The host found that Defender processes are maxing out 6 core CPU nearly entirely.
