A little while back generally once each login session, launching Open shell started causing explorer to hang. Had to terminate any other explorer.exe and launch a new one via task manager.
This I believe I have solved by upgrading the Intel HD Graphics 530 driver manually.
Intel® Driver & Support Assistant
I believe the problem started when Windows Update upgraded the driver.
The crash occurred usually within an hour of log on, but only after using Open Shell a few times.
I found reference on the Classic Shell forum to exactly this symptom; comments indicated it is triggered because it scans files in various areas (what for I don't know). Mention was made of an older Realtek driver for example, and .cpl files.
Example:

I followed the idea of using Sysinternals Procdump to get information on explorer hanging.
(Reliability monitor showed explorer hanging, but no useful information).
This listed two files related to the graphics driver, in
C:\Windows\System32\DriverStore\FileRepository\
Not exactly the first place you'd think to look.
I updated the driver from 23.20.16.4973 to 25.20.100.6471
Note that once explorer has crashed and been relaunched like this, launching troubleshooters from Settings fails (error message seemingly about permissions). Launching from the Control Panel still works.
So far no crash after several hours. But I need to give it longer to be more certain.
Have you seen anything like this?
