May 10, 2022—KB5013942 (OS Builds 19042.1706, 19043.1706, and 19044.1706) (microsoft.com)
On my system after installing this update, logging in gives a black screen and after a while you get to see the desktop. But then things don’t appear to work properly e.g. right click the task bar to start task manager and nothing happens.
You can start control panel and uninstall the update. After doing that things appeared to return to normal.
