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?

    Thank you for the update Rikk. Do we have to undo any of the workarounds after installing LRC V 12.3

    Hi, this update did not solve my issue, Lightroom Classic still crashes at the splash screen. I sat with Adobe support for hours yesterday and they even got remote access to my Mac where they tried a lot of things, got logfiles etc (Apple M2 Max / Ventura 13.3.1 (22E261). The support rep told me they will have to make a fix release to solve my issue. Should I create a new thread?

      Greetings all,

       

      Updates for Adobe Photography products have been released.  The April 2023 updates contain a final fix for this issue. After installing 12.3 it should be no longer necessary to monitor and delete the metrics.json file.

      If you do not see the update in your Creative Cloud Application, you can refresh it by hitting [Ctrl/Cmd]+[Alt/Opt]+[ R ].

      Note: It may take up to 24 hours for your update to be available in your Creative Cloud app.

       

      Thank you for your patience.

        @Rikk Flohr: Photography(and prerelease testers) Is this bug supposed to be fixed in LrC 12.3, which is currently rolling out?

        @TheDigitalDog Do you want to go back to previous versions? In Adobe Creative Cloud, select the product you wish to roll back, click on the three dots and select "Other Versions".

         

        Sadly, rolling back to the prev version does not resolve my problem.

          Honestly this is a joke. And I'm paying for this every month. This is sh*t that should be fixed before release of a product...

          FWIW, the bug doesn't affect everyone by a long shot, which is why it wasn't 'fixed' before release; it wasn't detected.

          There is no such file in the mentioned directory and there is no such option "Menu commend view details" so I am unable to perform the herein suggested bugfix. Extremely unhelpful merging all these tickets into one by the way...

            my LRC startup is terribly slow and takes 5 minutes

            - after starting LRC it waits for 5 minutes until it opens

            - after that it behaves normally

            - on MacOS Ventura

            - independent from which VR catalog is used (small or large)

            - during the 5 minute startup time the process says "Lightroom Classic (not responding)" and it uses 80-100 % cpu, which means it uses one cpu core

            - the problem appeared after i tried to connect one LR catalog to the adobe cloud to sync down images from the cloud into the LRC catalog. That worked in the first place but became slower and slower with more images (RAW) in the cloud. I went back to a catalog backup before I had it connected to the Adobe cloud. But since then LRC takes it's 5 minute wait until it opens

            - absolutely not acceptable for a professional software
