Yes the problem persists... I have rest option restarted and done other things. my PC is 64bit
OS Name: Microsoft Windows 10 Home
OS Version: 1803 10.0.17134 N/A Build 17134
Lightroom Classic CC 7.3.1
If Lightroom is closed and I insert a SD Card, Windows Explorer opens and display the files on the card. If Lightroom is Open and I insert the card NOTHING happens, not even Windows Explorer.
