LR Classic images don't show

So, looks like changing from library module to develop module has failed. I notice what appears to be the folders panel as in a library module component, but you are mostly in the develop module with that selected at top and the right side develop module panels show.

BUT, despite an image selected in the filmstrip, no preview in the navigation panel, no preview in the loupe panel, no previews in the filmstrip, and no data in the histogram, or curves. Both library previews and develop previews not showing up, and do data being sent to histogram, tone curves, and navigation.

Is your preferences file corrupt perhaps?

Hi @cbabwah! Welcome to the community! 😊

Could you share more details about the issue, such as what version of Lightroom Classic and operating system you're using? Did this start happening after an update to the app or your machine?

If you've recently upgraded your operating system, graphics card, or installed a monitor, this could be caused by a corrupted monitor profile.

1. Close Lightroom.
2. Go to System Preferences > Displays.
3. In the Color Profile pop-up, select sRGB IEC61966-2.1 for a third-party monitor or the default for your screen if it’s an Apple display (e.g., Apple XDR Display).

Finally, restart Lightroom and check whether everything looks correct. If it does, you’ve confirmed that the previous monitor profile was the cause of the problem. You can temporarily leave sRGB as the monitor profile, as it’s better than a corrupted one.

Hope this helps! Thanks!
