Hi there! I just updated my Mac to MacOS Monterrey and upon trying to open lightroom 6.0 it is crashing every single time. I don't mind updating to creative cloud at this point. BUT have I just lost 5 years worth of photography projects and personal images?? Mind you, I tried opening Lightroom 4.0 version and IT OPENS! and I still have access to all my old images. Any help on this? I talked to apple for about 2 hours. I talked to adobe for about an hour. No one was able to help.
If Lr 6 still fails to boot then go to the folder that contains the Lightroom Catalog which by default would be in your "users > Pictures> Lightroom" sub-folder. Open the Lightroom folder to display its contents as a list. You should see something like the screen capture below.
If there is a Lock file present delete that file and not any others. Do not delete the Catalog file.
After deleting the lock file double click on the Catalog file and this should boot Lightroom with your Catalog.
If there is more than one Catalog the info displayed could give a clue as to which one to use. The date last modified is useful.

You should seriously consider that, especially when running Monterey. LR6 is unsupported and a bit wonky (non technical term) under that OS. You'll be asked to update your old catalog, which as others have stated, have all your edits and such, your images still reside wherever they were in the first place. The old catalog will remain as a back up.
