grey thumbnails (underlying photo by double click) impossible to import to catalog

[abroe]

Hey, I recently upgraded my MAC (late 2013; graphic card:

NVIDIA GeForce GTX 780M 4 GB) to OS Catalina.

In Lightroom classic version 6 (desktop version Adobe Lightroom 1014445) my thumbnails are (completly) grey. If double click the underlying photo pops up (single view) but still it is impossible to import selected checked photo's or rather grey boxes into my catalog (import is from an external LaCie harddisk). I tried already Copy instead of Add but despite all my efforts it doesn't work...

So: the underlying photos are there but are not shown as thumbnails and cannot be imported into the catalog, although some of them are shown in the grid whereas some others (in the same folder) are not...

I uploaded some screenprints to show the problem. I hope someone can help me with this frustrating problem. Thanks in advance

What happens if you turn OFF GPU in preferences?

Already tried it. Does not help.

1.  It could be a faulty ICC display profile. Recalibrate and build a new one.
   2. It could be how the profile was built. Set your software to build Version 2 (V2) not V4 profiles.
   3. It could be the type of profile built. Try Matrix instead of LUT based profile. Again, that's a setting in whatever software you use to calibrate and profile the display.

1. A vent, please avoid using the attachment feature in this community page, it has never worked very well, and has gotten worse, it is not meant for images, it is not meant for text files.

moving on

2. Common issue post Catalina, this does not apply to MACOS pre Catalina.

Many people get tripped  up over pop ups that MACOS presents when a application first attempts to access various Files and Folders, mostly Folders. 

Catalina added cybersecurity for application rights. 

Outside of Lightroom, in the MACOS, on the MAC, bring up System Preferences, select Security and Privacy, select the Privacy tab. Scroll down to Files and Folders, for Lightroom Classic, and while you are at it, for Photoshop, make sure all boxes are checked.

If you store catalogs or photos in the MACOS system folder Photos, scroll up to Photos, and make sure Lightroom Classic, and Photoshop are included as being allowed.

After you made the change. Close Lightroom Classic, then restart your operating system.
