I rolled back to version 10.1.1 and LRC appears to be working now. Anything I can do to get 10.2 to work? in Windows? I even tried a accessing a backup and it failed.
Where you updating from Lightroom Classic 10.1.1 version? Did Lightroom Classic prompted for an upgrade? I am sending an email off-list. We can investigate your catalog.
Instead of starting Lightroom, go to the catalog and double click on it. That should automatically open Lightroom with that catalog.
If this does not work then try resetting your preferences file. There are are a multitude of examples on this forum as well as on the Lightroom Queen website.
Still not working, clear your previews. Hate to recommend that as it can take a long time to rebuild them.
Lastly there's the possibility that one of the Lightroom files is corrupt and that a reinstall is needed.
Hopefully someone else has a better idea.
Tip: hopefully you externalize all edits. If not, do that first. Then you can create a new catalog and import all your images without losing your edits. Edit history is lost but the final result is kept. Let's say that you moved the Contrast slider 3 times for a given image. History shows all 3 steps while only the net result is externalized. You will also lose your albums, create a keyword for each album and then you can easily recreate them through you will have lost your reordering.
Since the 10.2 update on Monday, this is the only report I can recall seeing. I would say this not a returned issue but likely a completely different issue.
I would recommend opening your catalog in 10.1.1 and letting it sit idle for 5 minutes.
Close Lightroom 10.1.1
Make a copy of that catalog via the file system
Install 10.2.
Open the original catalog from step one
Screen shot the error. if it won't open and post it here.
If it fails, Zip the catalog from step 3 and I will send you instructions.
@Rikk Thanks. I followed these steps and they worked.
I also re-opened my new 10.2 catalog (using LrC 10.2) several additional times to be sure.
There must be something about the 5-minute wait time. During that wait time, the additional "*Sync" and "Mobile Downloads" files were magically created.
I will test daily for a few more days to be sure this fix has really taken hold.
Now, after a couple of days, I re-tried LrC 10.2 and (surprise!) it successfully opened my catalog. (21 March)
Strange.
I did not touch LrC, nor my files, folders or photos, in the intervening period.
This time, a "verifying integrity" message box popped up briefly before the catalog fully opened.
Understandably, I am quite "spooked" by this behavior. I will check periodically to see if this issue is really gone.
I am not a professional, and I (thankfully) don't use LrC for work. But I am photo enthusiast and I am naturally concerned about ~20 years of photos and edits.
After ~16 hours (overnight) with no other usage of this computer, the catalog opened on the first try. "Integrity check" message box popped up briefly. (March 23)
My iMac is not showing any other kind of odd behavior.
Could this be related to some Adobe cloud/sync intermittent issue? When this fails, is my LrC 10.2 instance reaching out to some online Adobe service that it cannot find?
When I update Lr classic this error “ Unexpected error opening catalog; choose a different catalog, try again, quit” happens. Anyone have any ideas how to fix this? My Mac needs to be updated to Big Sur 11.2.3 (I was waiting for the next version to update). Lr works fine when I go back a version. I called support and tried their chat and it was a waste of time. I have a Mac using Big Sur.
I'm sorry Adobe but over the last 12 months every time there's an update there seems to be a problem. If it's not Media Encoder then it's Lightroom Classic. There was a similar issue to this in December and then a new update resolved that problem and now it seems similar is happening again.
This thread is being merged into an existing authoritative thread for better tracking and response. Please review the official answer (if any) in the second post on the thread for more information.
When I upgraded from LrC 9 to 10, I started having catalog problems. After the catalog was upgraded, the LrC would launch once, then not launch again without testing catalog integrity upon startup. I tried backing up, restoring backups, creating a new catalog and importing the old one -- all the same result. Now after updating to 10.2, it's worse. LrC won't even give me the option to select a catalog and test integrity - it just closes. I uninstalled, wiped prefs and re-installed, then tried again with a new catalog. The same outcome -- crashing immediately after launch. So LrC is unusable, and I can't roll back the catalog to v9 to use older software.
