Question

LR Classic (current version) wont open on Windows 11 PC

It works fine for a few days and then won’t open.  Task Manager says it is running but I see nothing.  What gives?

I should mention my catalog is huge … don’t know if that has anything to do with it.

    Your symptoms are just like I had when a new set of ram was defective causing the catalog to be corrupted. I’m not saying your issue is related to ram, only to a possibly corrupt catalog. Be sure any .lock file in the Lightroom Classic folder is deleted, then try a backup catalog.

    I have just had a similar problem- Nothing starts visibly except for intense hard-drive activity. No error messages. Repeat clicking of the LrC start icon results in multiple listings of LrC in Task Manager.

    For some reason (went for a cuppa?) I let it continue with its disk activity thinking it might be a scheduled backup and eventually after about 10-15minutes it finally opened my catalog.

    Since then the catalog has been opening and closing as normal, or even faster to open.

    So I don’t have any answers and cannot explain what happened. These glitches are sent to try us!

    I have left it alone and come back to nothing … maybe I needed to wait longer …. so frustrating that this program I have come to depend on is so buggy ...

    I waited 45 minutes after “opening” it and it came up today ….  Geesh.

    If Task Manager “says it is running”, then end the task using Task Manager. Right-click where it says Adobe Lightroom and then select “End Task”. Wait a minute or two and try opening LrC.
