LIghtroom Classic

Also, screenshots, a picture is worth a thousand words.

So, for all four of your postings today, accomplish the following (please)

In Lightroom Classic, click on Help, then click on System Information, then click on Copy.

Paste that into a reply (post) on each of your problems.

Please only include the information from line 1 down to just past the plug-in info. All that stuff after the plug-in info is just so much useless info to the issue(s)  at hand.

This will provide several bits of verifiable info

Lightroom Classic version actually installed

Lightroom license status (rarely an issue)

Computer Operating system version/build

Display settings

GPU make/model, and GPU driver version (yes, I know, more helpful on a WIazN OS, as you can not change it on MAC)

Plug-in's installed (some are known to be buggy)

etc

And, your camera model & number is..?

Your operating system & number is..?

What do you see?   Totally blank screen? Grey thumbnails?  A screen-clip is helpful!

What is selected in the 'Source' panel of the Import dialog..?

What is selected in the 'Destination' panel of the Import dialog..?
