Windows 11 Defender blocked “severe” and removed Synology Plex Server update 1.32.3.7192-7aa441827-x86_64_DSM7.spk due to suspected Trojan:Script/Wacatac.B!ml.

Never seen this issue before. Would appreciate recommendations to resolve.

Either wait a few days and try again
or inform Microsoft of the issue. They are responsible to prevent false alarms of their AV software.
(Provided that the file in question has been downloaded directly from the plex.tv website and not from some 3rd-party server.)
