Lightroom Classic V 12.2.1 hangs at the banner and will not open

[allentim1947]

Yesterday I closed Lr classic and it took 4 minutes to close without saving a backup cat. When I tried to reopen Lr classic it opened the banner and then would not go beyond it. I Forced Quit it. I opened Lr Classic again and let it run overnight. When I got up it had opened Lr Classic. I then restarted Lr Classic and it hung on the banner. I let it run for 2 hours and it forced a reboot of my Mac. I deleted the app and reinstalled it with an older version. That did not help. I then installed an older version of the catalog and that did not help. I know that Lr Classis was trying to open it because I watched my RAP go up and down. I'm running Mac OS Monterey 12.6.3 Please let me know what suggestions you have to fix this issue.

As you have forced closed LrC, I assume that you keep have you deleating the errant lock file

have you considered resetting the preference file?

Unfortunately, your suggestions did not resolve the problem. Lr Classic is still hanging on the banner.

There does not seem to be a "lock" file in my Lr Classic menu. I've included a screenshot of the Pictures files.

I did change the file name for the Adobe preferences.

I'd sure welcome some additional help.

Thank you for your suggestions. I tried an older catalog and a default catalog.  I tried an earlier version 12.0 and it still takes Lr Classic 82 minutes to load. Once it loads, it works fine. I checked other programs including Photoshop and they load at their previous speed. Something is causing Lr Classic to load slowly. Any other suggestions? If not, I may have to live with the slow load rate or take my computer to a repair shop.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

mostly interested in CPU, RAM, GPU (and driver version), library location (as LrC reports it) and Plug-ins

Ok, your screenshot show the library in your main hard drive, and not some sort of share.. Still interested in the remainder.

You might also want to try launching LrC while logged into your MAC as another user, typically by using the Admin account. This could point to user account and/or rights issues.

[allentim1947]

I did create a new user account and logged in using it. I signed into the Creative Cloud and launched LrC. It launched very quickly. It appears to point to a user account and/or rights issues. This may be outside of your area but I need to correct these issues since all my files are connected to my current user. What would you suggest that I do? Thank you.

Account/user rights issue indicated by logging on as other user

See:

Troubleshoot unexpected behavior in specific user account | Adobe

and

Basic troubleshooting steps to fix issues in Lightroom Classic | Adobe

/followup/

Apparently solution was in first link, For MACOS Solution #4 ( Delete account-specific Adobe cache files.)   and specifically involved Library CACHE

That screen capture if the volume your catalog is in, some oddities noticed, some of these are just user preferences, some are "what the heck, am I reading that wrong. 

• Looking at your catalog catalog, library previews, etc, modified today, but with added date that makes no sense. Is your computers clock correct? What date/time is it showing? Or is that a MACOS thing.
• Catalog is on your main hard drive.  How much free space in percent (that is % not Gb) remains? Looking for at least 20%
• Do you have additional hard drives?
• Looks like you keep backups on the same hard drive as the source. Bad. Hard drive dies, originals and copy's die.
• It appears that you store presets with catalog (or did at one time), This would have nothing to do with the problem. Do you have others edit the catalog? Typically a pro cooperative as in a business?  Ok, just being argumentative, never mind that one.

[allentim1947]

Here are the answers to your questions:

1. Yes, the Date and Time are correct.

2. I have a 2T drive on my iMac. There is about 320g left.

3. I have 8 additional drives to store my photographs and LcC backups. They are connected to my iMac. I also have a larger drive where I have my Time Machine Backup updated every hour.

4. My backups are kept on a separate drive, one of the eight. I also use BackBlaze for backup for all of my drives less the Time Machine Backup.

I believe this answers your questions. Thank you.

Hi!

I had the literal exact issue and followed almost exactly same troubleshooting you did.

The only thing that worked for me was to follow step 4 for MacOs on one of the links posted above by GoldingD. Basically, to delete the cache folders. I deleted the folders "Adobe", "Adobe Camera Raw 2", "com.adobe.lightroomCC", and "com.adobe.LightroomClassicCC7" under ".../USERNAME/Library/Caches/". I then clicked on the LrC icon and it booted in literally 1 second, albeit with no catalog loaded. I then chose my latest catalog, restarted the app and all is good now.

I also had this exact issue, and the cache solution worked for me.  Thanks!

[allentim1947 · Accepted solution]

Getting rid of the cache worked. I follow the instructions posted by GoldingD https://helpx.adobe.com/x-productkb/global/troubleshoot-unexpected-behavior-user-account.html and focused on your suggestion of #3.

I want to thank everyone who helped with resolving this problem. It's a great community.
