This is a reproducible crash that I have found in Lightroom Classic 7.3 running on a Windows 7 Pro 64bit OS Toshiba laptop fitted with a built-in SD card reader.
Follow these steps to reproduce:
1. Launch Lightroom Classic 7.3 and ensure that Auto Import is disabled and the Preference 'Show import dialog when a memory card is detected' is unchecked.
2. Insert an SD memory card. Close the Auto Play dialog if it is displayed.
3. Use the Safely Remove Hardware icon in the system tray to Eject SD Card. An error dialog is displayed stating that 'This device is currently in use...' Click OK to close the dialog.
4. Open Windows File Explorer, click on Computer to show Devices with removable Storage. Right-click on the SD card icon and select Eject from the pop-up context menu. An error dialog is displayed stating that the drive 'is in use' and to 'Save any open files on this disc...' In this dialog you have three choices: Cancel, Try Again or Continue. The dialog states 'If you choose to continue, the files will be closed, which might cause data to be lost.' Click the Continue button and the SD card is ejected.
5. Lightroom has how crashed with the busy cursor whirling away and (Not Responding) displayed in the title bar. Lightroom must now be forced to close.
Following these steps while Lightroom CC version 6 is running does not crash LR6.
So, why is LR7 opening files on an inserted SD card? There is no reason for LR7 to be accessing the SD card at all at this stage and it certainly shouldn't crash when the SD card is ejected.
Would other LR Classic 7.3 users try this too and report the result?
I would like a proper response from the Adobe team on this and by this, I mean someone who actually has the authority to do something about it. If I don't, I will assume that the development or management team are not interested in fixing the problems that infest this version of Lightroom.
