Answer
A recent Microsoft update has caused a number of circulation and searching issues in Polaris for the following Microsoft Windows Operating Systems:
2016 - KB5071543
2019 - KB5071544
2022 - KB5071547
At this time, it is the recommendation of Polaris Support to uninstall the update if it’s already installed, or block it from installation if it has not yet been applied.
Update:
Microsoft has fixed the aberrant behavior, which is available for Server 2016, 2019 and 2022, respectively:
