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?

@evan.sante 

I've reviewed your posts and do not find where you've posted this issue previously. I would be happy if you could send me a link to your report as I have missed it. I would also make your original report the primary thread for the bug report if you like.

@evan.sante That's normal, usually only one prerelease person logs a bug even if multiple people can reproduce it... just like there's one bug thread here but multiple people commenting. He just meant there's already an internal bug report open.

I deleted the metrics.json file on my system and now LrC boots much faster than it has been for many months.

After deleting the file and booting the LrC application it was still slow for the first restart.

However subsequent starts have been much faster. The metrics.json file has been rebuilt but it's now much smaller. See the screen captures.

I find it disingenuous that you say ONE of your testers had a bug log for this over the past 2 weeks I've had 4 clients that I work with report the same issues, in addition to myself.

 

You might want to point out that it's NOT the Lightroom CC Folder which also has the same JSON file.  - CES

What purpose does the " metrics.json file " have and is it a file that is created by Apple operating system?

Removing the metrics.json file fixed the issue for me.  About two weeks ago LRC 12.2.1 started taking 30+ minutes to start up on my Mac.  Similar behaviors as others on lack of LRC window while LR process in acitivity monitor says "not responding", and consuming large amounts of CPU but if left to start up would eventually start up after 30 minutes and function fine after that for the most part.  I also noticed once started my mobile sync would stop working until I restarted LRC, and waited 30 minutes for it to start.   When I deleted the metrics.json file it started right up as normal/expected.

Hi,

 

This morning, Mar 28th, 2023, I was editing a couple of photos. Exit LrC and the backup happened.

Return from work and I was ready to start editing again but LrC just does not open. I read other threads about the topic first. I tried to reset the preferences (Alt-Shift routine) but that did not work. Uninstall LrC from the Creative Cloud App and install it again. Now I get a non-responsive window about Catalog Upgrade.

 

What is happening?

Update:

The Catalog Upgrade just created a new catalog. It did not upgrade my current catalog. After Lightroom opened, I tried to open my current catalog and the whole nightmare started again. Now, not even the newly created catalog can be opened. Only a black strip on the desktop shows up

I can also confirm that this solution worked for me. I'm running Ventura 13.3 and LrC 12.2.1. Prior to 12.2.1, I had no issues.
