1. Submiting a crash repoert.

That screenshot is a Adobe Lightroom Classic Crash report. If you get it again,, you should fill it out, filling in what happened, what led to it, and filling out your e-mail address, then send it. 

You might want to refer your LrC Community discussion in the text (include a link) .

2. Screenshots in Windows

Your photo of your monitor worked Ok this time. In this case it was a simple pop up screen that is well known. But in the future, pleas use tools on hand to take a proper screenshot. Your Windows OS includes that.

Restart the computer, see if the problem goes away. If not, you likely have a corrupted catalog file and you will need to restore a recent backup of the catalog file.
