Unable to open Lightroom

Hi ​@Bubbly_impression5CD5, Welcome to the Lightroom Community forum! To better help you with this issue, we would like a few more details. Can you send your system info and a screen recording of the issue with the error dialog? You can find your system info by going to Help > System Info, copying and pasting it into a text file, and attaching it here.

In the meantime, please try manually resetting your Lightroom Preferences: https://adobe.ly/4o7JADQ and see if that helps. Thanks! ^CH

Please post a screenshot of the error dialog.
