When I insert a USB memory stick a window opens, as expected, inviting me to "Open in File Manager".
However, when I press OK, I get a message:
The specified directory '/media/pi/E1D1-A752' is not valid
where E1D1-A752 is the id of the memory stick. The subfolder is not created.
I am running the system from an SSD on a RPi4, where I have copied the system from the SD card, and changed cmdline.txt in the SD /boot folder to run the system from the SSD, as described on many websites.
The following are results after receipt of the error message:

I can mount the memory stick manually without problems.
Any suggestions would be appreciated.
