  • 25 June 2024 It's Lightroom update time again! See What’s New in Lightroom Classic 13.4, Mobile & Desktop (June 2024)? for the bug fixes and new lens profiles. Warning... this is a minor dot release and does NOT fix some of the bugs introduced in 13.3, so if you reverted to 13.2 due to bugs (e.g. sync issues), we'd suggest you stay there for now.

I posted this bug report this morning Sept 26.
"Switching from library or map modules to develop module results in a black screen.
Switching back is normal.
The only way to edit is to shut down the application and restart.
I am using Windows 10 Pro Build 17763.737. This bug came with the update installed 2019-09-25. "
Posting here just as a heads up.

If that was really a bug in Lightroom, complaints would be all over the place. More likely it is a problem with your graphics card. Make sure you have the latest version of the grapics card drivers. And try to disable the GPU acceleration in Lightroom: Go to preferences - performance and turn it off.
I cannot reproduce what you experience.
But I am using the latest Win 10 Pro build : 10.0.18362

Try updating to the latest one.
