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?

Edition Windows 10 Pro
Version 22H2
Installed on ‎17.‎03.‎2023
OS build 19045.2728
Experience Windows Feature Experience Pack 120.2212.4190.0

Thank you so much for your help. But I can't even open LrC.
I immediately get a pop up with a system error.

I'll try to translate, because it is in Dutch 😉

Lightroom.exe system error
The code execution cannot be continued because dunamis-ingest.dll was not
found.
You might solve this problem by re-installing the program.

I get 4 of these pop ups in total, but with a different file:
ahclient.dll
ui.dll
substrate.dll

Don't know how to re-install either 😕😕
I just have a subscription and downloaded.
No idea how to re-install it.

Kind regards
Frieda

YEP... this did it. Un-installed then reinstalled and renamed that bad file. DID NOT happen in previous versions over the last 6 years. The newest version is a disaster... even a photo I was editing suddenly disappear from the Windows version library while still showing on my synced phone. Photo appeared after this workaround.
Hopefully will get fixed soon as this is making LRc not usable. Thank you!

I had issues with editing stitches with the transformation/straightening tool. It was terribly slow waiting for the lines to show up and the loupe showing details.

Renaming the metrics.json file solved the issue, it was really fast directly after.

@Henry9808 , Make sure you are checking for the file when LrC is closed. No file will be present if LrC is open or running in the background.

@Henry9808 Lightroom Classic must be closed to see the metrics.json file. Make sure you have closed the Application.

@David J Wood I have received a link to the file and passed it onto engineering. Thank you.

What does one do if there is no Mac: /Users/<username>/Library/Caches/Adobe/Lightroom/metrics.json file? I am having the same slowness in loading issue (14 minutes) as well as the same import / export issues and preview problems others are reporting. Lightroom is pretty much useless at this point so any suggestions would be appreciated.

This seems to be a much bigger issue than just deleting the JSON file.

With one of my clients, who had a very old machine, we decided to buy a new computer.

After deleting the JSON file on the old computer, I created a backup and optimize the catalog. We then moved ONLY the catalog file and the data file created from ZIP file, to a new folder (on the new machine, and started Lightroom). Lightroom then rebuilt the thumbnails.

1 - Right from the start, we started to see some of the issues that have been reported such as when you switch to the develop module it takes much longer than normal for the image to render (10 to 15 sec, if it did it all), forcing us to go back to the grid view and then go back to the develop module in order to see the image rendered and had the ability to edit it.

We’ve then created a 1 to 1 preview for another image, same issue as above.

2 - On a Brand New installation of Lightroom, clicking on the export button does nothing! after restarting Lightroom, and clicking on the image, doing a simple crop, and then clicking on the Export Button, had to wait 3 to 5 seconds before the export dialog box opened, if it did it all. This issue persists throughout the session, the only thing that slightly improves it is restarting Lightroom.

3 - I then started a built 1x1 previews for 25000 images, when my client woke up he got "Your system has run out of applications memory" see attached. Closed Lightroom and when he restarted Lightroom, the catalog, which is on an external drive, could not be found.

You have to remember that this is on a brand new top-of-the-line MacBook Pro 1TB 32 gigs RAM, with only Creative Cloud and Lightroom on it.

I’m just saying these issues are NOT normal and cannot be tied to a single JSON file.

It's obvious that Lightroom has changed the way that it handles memory management, and it simply does not work. These issues are almost identical to the issues back in Lightroom 3.0 which was far and away the worst release of Lightroom.
