P: LrC 12.2.1 fails to start/launch or is extremely slow launching.

Hi,

 

LRC 12.2.1 is not starting anymore, just launches as a background process using significant amounts of RAM and CPU, but the visible window never shows up. 

 

I have already:

- Tried the alt-shift-click thingie.

- Tried logging out and in from CC.

- Wiping all data files from the computer and letting LRC create a fresh Lightroom folder and catalog file (sometimes it does that, sometimes it hangs before the folder is created). 

- Wiping all Adobe products with the cleaner tool and reinstalling just LRC.

- I have even formatted and reisntalled the computer (becuase it was a good time to do that anyway).

 

But LRC still fails. What to do next?

    This does not work for me. I have a Mac with Ventura 13.3.1 and Lightroom classic 12.2.1. I don't think I changed anything and now it doesn't start. I've tried launching with default preferences. I've deleted and reinstalled. I've deleted Photoshop and others adobe products. I updated my operating system. I've deleted the metrics.json file. No luck. I have the "Problem Report" that is getting sent to Apple. Any other suggestions?

    Yes - I just found that and it worked like a charm.

     

    Many thanks (sorry - didn't spot the pinned post in my searching).

        Try deleting the file "metrics.json", following the precise steps here:

        The process can be a little persnickety, so follow the steps exactly.

          LRC is running very slow.  My 2020 Apple desktop is using Ventura 13.2.1.  Memory:  32GB 2400 MHz DDR4.  Graphics:  Radeon Pro 580A 8 GB.  All Apple Care could tell me is that it is a LR issue.  And in truth, this slow down only takes place when I use LRC.  I typically process 30mb Raw files from my camera.  Any assistance would be greatly appreciated.

          Thanks

          Pete

          Lightroom Classic won't start after installing Lightroom on macbook pro running Ventura. I tried unintalling both, restarted my laptop  and reinstalled Lightroom classic, restarting laptop again. No luck - I have to force quit using activity monitor. I tried restting the preferences by holding shift-option while clicking the icon and the porgram still hangs up and I have to force quit. I tried double clicking my catalog file and that doesn't work either. Any ideas?

          Thanks for all the tips and tricks. Lightroom Classic is working again and hopefully that metrics.json file does not get created. The original was 9 GB of pointless information. So happy there was a way to get rid of it.
