Metadata syncing problem

[goughy]

I am having a serious problem with Lightroom which started about a week ago.

I am running Lightroom 8.4.

I have about 20,670 photos in the cloud using 143.2 GB of my 1TB allocation.

My 2022 Mac Studio has an Apple M1 Max chip, 32 GB of memory running Sequoia 15.5.

A Speedtest of my Internet connection is currently showing about 900 Mbps down and 870 Mbps up.

My desktop Lightroom has been showing “Syncing items” for about a week now. It started after I tried to reset the star ratings and flags on all my images.

Response is very slow, especially when closing Lightroom and loading grid view.

No photos show any metadata when I select the Info icon and all show “Syncing Metadata…” However closing Lightroom and reopening on the same image will show metadata for that image.

Similarly, some photos show greyed out sliders for editing but this is not consistent. Closing Lightroom and reopening on the same image will show active sliders. These last two issues might be a result of the slow response.

I do not have these issues when I use Lightroom 10.4.0 on my iPhone.

I suspect that the metadata syncing has somehow got stuck in a loop or is very, very slow.

How can I resolve this issue?

Please restart your computer and then launch Lightroom Desktop.

If the metadata fails to resolve within an our, please generate a diagnostic log.

For LrDesktop

• Go to Preferences
• Account Section
• Hold down the [Opt/Alt] key to make the [Diagnostic Log] button appear.

Thank you, Rikk.

A clean install and restart dd not help.

I have generated a diagnostic log.

Please upload the diagnostic log to a file sharing site, (Dropbox or similar) and share the link with me. 

Thank you!

I've uploaded it to Dropbox at https://www.dropbox.com/scl/fi/3zba9udpqxxfce0hfs505/DiagnosticLog.html?rlkey=rx6tef7lynt3g4nsy7jk57...

Got it. Thanks. Please standy by!

Following the same steps could you please generate a [Sync Status Report] also?

Thanks

Had a problem generating the Sync status file. I've shared a link to a diagnostic zip file.

I have now reset the local cache file "Lightroom Library.lrlibrary" and after the initail re-downloading the problem seems to have gone away. There might still be some issues I haven't found yet but at the moment it's responsive and working as expected.

Thanks for your help.

It is great things have been working.

Engineering is still trying to run this failure down and has asked if you can provide additional information:

"Ask the customer:

• for information about what version of Lightroom they were previously using
• if they have a non-standard drive setup, or use any tools like Dropbox or iCloud to backup their Lightroom catalog
• to run a disk check to verify make sure their hard drive is okay. The customer is on a Mac, they can use Disk Utility to check HD health:
  
  Open Disk Utility: You can find it in Applications ->Utilities, or by using Spotlight search (Command + Space, type "Disk Utility"). Select your disk: Choose the hard drive you want to test from the list in the sidebar. Run First Aid: Click the "First Aid" button and then "Run" to initiate the diagnostic process. Review the report: Disk Utility will report on any errors found and attempt to repair them."
  
  Thanks.

Previous version of Lightroom was 8.3.

The problem occurred with Lightroom, not Lightroom Classic. I also use Classic and that catalog is backed up to my main drive using “Once a day, when exiting Lightroom” setting. I use Time Machine to backup my main drive hourly to a 5TB Seagate BUP Portable Media drive. No Lightroom files or image files are backed up to iCloud or Dropbox.

Disk Utility reported no errors on either the main drive or my Seagate portable drive after running First Aid.

Hope this helps.
