Lightrooom Classic Not launching

A separate inquiry, but related

I will assume that you have a LrC startup icon down in your Taskbar.

Hold down on the ALT key while clicking on that LrC startup icon. A Select catalog screen should appear. Select a new catalog. Does LrC start (in a new catalog)

Or as JohanElzenga described above.

Your catalog could be corrupted, and uninstalling/reinstalling does not deal with the catalog. So try this: temporarily rename your catalog folder, so Lightroom can no longer find it. Then when asked, create a new catalog and see if Lightroom does finish the start successfully with that.

I did have a problem in the middle of last month where I had to have the catalog repaired and it worked fine. Now when I try to launch it won't open. I went and deleted locked files I saw per other posts I read. It still won't launch.

First up, can you attempt to launch LrC in the following manner

1. Do not start LrC (in this test) by clicking (double clicking) on a startup icon.
2. Use Windows File Explorer, to navigate to your catalog.
3. Delete any lock file.
4. Double click on the catalog

After doing that:

1. Does the LrC splash screen appear
2. If the Splash screen appears, does it get stuck at reading preferences.
3. Or did nothing happen.
