UPDATE:
Due to the lack of complaints regarding this firmware update worldwide, I am assuming the issue was mine only. The firmware is assumed to be okay.

It could be that Surface Firmware 390.3192.768.0 from April 16, 2020 causes extremely poor performance after installing.
This happened to both of my Surface Book 2 units today. After the firmware update and the Surface is restarted, all seems well for a minute or two. Then, OneDrive does not finish syncing, and programs and apps can take up to 3 minutes to start (Edge, Office, Microsoft Store, 3rd party programs and apps). I tried isolating the problem by one-by-one disabling networking, iCloud, SMB services. Finally, disabling Windows Defender Virus and Threat Protection for 3 minutes then re-enabling fixed all problems.
It could be that Windows Defender was somehow detecting an infection or other system issue, and could not resolve it, until restarted.
