Will not launch

[kennedyalex]

I cannot get Lightroom Classic to launch, at all. I have uninstalled, reinstalled, kept preferences, removed preferences, restarted my computer. The task shows up in task manager and creative cloud says it is running, but absolutely nothing else happens. I am up to date with 12.5, so I know that's not it. I also tried just installing 12.4 to troubleshoot and I'm having the same problem. Is anyone else experiencing this issue? I start semester (photography degree!) Monday so I really need this to start working again. Thank you!

I'm running Windows 11.

Your catalog may be corrupted. Open the catalog folder and move the catalog file (the file with the .lrcat extension) out of it. Then start Lightroom. Lightroom won't be able to find the catalog, so it should ask you to locate it or create a new one. Create a new one to see if Lightroom functions normally with a new catalog. If it does, then you need to replace your catalog with a backup copy from before the problem started.
