Import bug in Lightroom Classic (v8.3)

Lightroom Classic (v8.3) has been hanging for anywhere from 30 sec to 3 minutes when I click import. When the import window finally comes up, it is very slow to respond.  Import is the only Lightroom feature having performance problems.

I tried turning off the GPU, disabling virus protection, disconnecting all external hard drives, and several other suggestions made by users in the Lightroom forum.  Nothing helped.

But then I opened the same catalog with Lightroom Classic CC (v8.2.1).  Import responded normally!

I'm on Windows 10 after a recent upgrade from Windows 7.  Before the upgrade I was running v8.2.1.  After the upgrade, I installed v8.3.  I had assumed the problem had something to do with Windows 10.  But my experiment with v8.2.1 on Windows 10 points the finger at v8.3.

Do you have an Android device attached via USB to your system? If so, does disconnecting it cure the slow startup to import?

I was too quick posting the bug report.  Continued use of v8.2.1 shows that it also hangs when I click import (Lightroom not responding in title bar, blue circular cursor) as well as synchronize folder.  However v8.2.1 does not hang for nearly as long as v8.3. 

The only attached devices are my keyboard and a printer (which is not turned on).

I also have a performance problem with importing. I'm also in Windows 10, and importing files already on my disk, so the input device is not relevant. I think the delay is related to LR trying to construct the thumbnails, which seem to take quite a much longer time to appear.

I'm guessing that you have Lightroom set to import automatically when you insert an SD card.  I don't.  When I click Import, the import window comes up with no thumbnails in the main window.  However it comes up with the source panel fully populated (the panel on the left, showing your files and devices), and this could be what's taking a long time.  Lightroom needs to get this information from Windows.

I have noticed that when I select "This PC" in File Explorer (it was called "My Computer" in Windows 7), Explorer itself becomes unresponsive while a green "progress" bar moves slowly across the address field.  I assume Explorer is scanning the entire computer for all files and devices.  It takes a long time!  I do not recall such a delay in Windows 7.  Now I assume that when you click "import" Lightroom must be asking Windows to scan the PC in much the same way.  If so, this may be the cause of intolerable delay.

So I searched Google for suggestions on speeding up File Explorer.  One article suggested that Cortana slows it down.  So I disabled Cortana.  I opened a File Explorer and selected This PC.  I got the green progress bar, but only for a second.  Good!  So I restarted Lightroom and clicked Import.  Import came up instantly with my entire Folder hierarchy in the left panel. 

It may be too soon to declare victory, but I thought I would share these preliminary results.
