I had the same issue after upgrading to the Unified Agent and updating the Sense client to 10.8048.22439.1065. Updating to - KB5005292 (Version 10.8049.22439.1084) seems to have fixed it for me. You can get the updated Sense Client from https://www.catalog.update.microsoft.com/Search.aspx?q=KB5005292
and verify that Client has updated by running the following PowerShell command

Exactly the same scenario and seeing the same issue.
Seems to be much more impactive on one of our 2012 R2 servers than others which shows a constant stream of "Query Directory" C:\Windows\System32\catroot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\*.cat by MsSense.exe
