What is the source of import?
Please share your Lightroom Import window screenshot for further assistance.
Other settings are not included in this screenshot like if you are adding or copying.
Would suggest you to switch to Copy option while importing and expand destination panel which should display the images in the selected folder.
You can then switch back to the normal settings that you want.
If that does not help, could you please share the complete settings which includes other settings as well.
Does it remain the same when you choose Copy at top and expand the destination panel on right?
I restart lightroom, and dit again what you asked.
It works now. Could I have this again? What happened?
In any case many thanks.
Lightroom was unable to read the location for the images to be imported.
It was just random and should not happen again.
Good to know that its working now!
