Photos not being displayed in Lightroom Classic

I have suddenly been unable to view my photos in Lightroom Classic.  What do I need to do?

What do you see? Describe in detail. Also, show us a screen capture of what you see (use the "Insert Photos" icon; do not attach files)

In a first step try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If you see in the library only grey rectangles your monitor profile could be corrupt.

If this also doesn't help we need more informations about your environment.

Which operating system do you use?

Which version of Lightroom do you use?

Please provide also a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

Is your system up-to-date? Do you have all recent patches and updates for your operating system and device drivers (esp. graphic driver) installed?
