Lightroom Crash and cannot reopen catalog

This has happened many times. Lightroom crashes because it cannot handle its own features (HDR Merge and Panorama). It crashes and when I try to open the application again, it say Catalog is being used already. It is not. No applications are open, I have force quit everything. There are no ways for me to reopen Lightroom with all the photos I need. Just small batches of photos. This is unacceptable to be happening for problems your app creates. I have to restart my whole computer to get it to reopen again. How can I fix this, how can this be solved so I don't have to shut everything down because of your crappy interface.

I find no crash reports in our system under this email address and Lightroom Classic 8.4.1 or Lightroom Desktop 2.4.1 (You don't say which you are using and you've tagged the thread with both products). Whose crash dialog are you seeing? Apple's? Microsoft's or Adobe's? Are you submitting the report when asked?

Also, please go to Help>System Info... and get us your exact installed Lightroom version number.

I was a Mac IT pro for 25 years. Sometimes it’s the MacOS that’s the problem.

To rule out a corrupt cache or application state damage, please give your Mac the "once over"! Run the free Onyx (, select the Onyx version for your OS, download, run it, reboot. 

In Onyx run almost everything in the Maintenance tab, deselecting things you may not want deleted, like Launch Services . Hit the "Options" button and deselect more stuff like Cookies & Other Site Data, Browser History, Form Values, etc. If you don’t know what something is, google it, or don’t run it, or ask me, I'm happy to reply). Then hit Run Tasks. After it's done it will ask for a reboot.
