P: Unable to relaunch after File>New Catalog/Switching catalogs, or relaunching with certain plugins

[Poutchiou]

Hello, I just updated LR Classic from v14.4 to v14.5 on Windows 10.
I’d like to report a major bug:

• It is impossible to create a new catalog from within the application (Menu > File > New Catalog).
• It is impossible to switch catalogs (except by clicking directly on the catalog file to open the application).

The window App closes, then nothing happens for several minutes (Task Manager shows a "zombie" Adobe process still running) → I have to kill It to reOpen the app.

I had to reinstall version 14.4 and everything is now working normally again.

Apparently Lightroom Classic 14.5 doesn´t shut down when Midi2LR 6.2.0.1 is running.. See https://community.adobe.com/t5/lightroom-classic-bugs/p-unable-to-launch-lightroom-after-menu-gt-fil.... Do you have this plugin installed?

[gryphon1911]

As a matter of fact I do.  Would I need to stop Midi2LR and then shut down LRc?

1. Start Lightroom Classic. 

2. In File > Plug-in Manager, select the plug-in and click its Disable button. 

But that might not take effect until the next restart of Lightroom Classic, so you might have to go through one more force-quit. The next time you start Lightroom Classic after disabling the plug-in, it should quit normally if that plug-in was the only problem.

I was pointed to this thread from another forum after discussing a problem there about Lightroom Classic 14.5 hanging on quit. It was recommended that I add my info to this thread. At some point (not exactly sure when), Lightroom Classic 14 began hanging after I did a standard File > Quit in macOS 15.6.

I traced it to the plug-in for the TourBox control surface. I currently have the plug-in disabled and Lightroom Classic can now quit properly again. I’ve been using their software for most of this year and don’t remember the plug-in causing any problems before, so is this because of a change in Lightroom Classic?

The plug-in version is the one included with TourBox Console software version 5.9.2.

@Rikk Flohr: Photography  Like @ShootingPixelsAndy, I have experienced this problem with all versions of LrC14, if not earlier versions. I've used the "kill zombie instance" countless times in the past. I use several plugins (see attached list), but none of them are considered critical in this thread.

Sometimes it didn't even help to remove the zombie instance - trying to open Lightroom after killing it immediately ended up in a "zombie state". In these cases, I had to open and quit Lightroom Desktop to be able to open Classic.

I have not encountered any such issues with 14.5 so far but I have not used it very much yet.

I really hope that this bug report will put the team on the right track to find and fix the general, underlying issue.

I am using LRC version 14.5 on Windows 11.

Everthing was running fine until yesterday when I quit LRC and tried to open it again, I would not.

I have to go to the Task Manager and end the task in order to be able to open it again.

I tried with severals catalogs, same thing.

I thought maybe Lightroom is organizig the catalog, I let run for the WHOLE DAY, it would not stop,

here is a screen grab from the task manager

I Have to end the task in order to be able to open LRC again

LrC Vers. 14.5 lässt sich nach Beenden nicht mehr starten. Im Taskmanager läuft das Programm im Hintergrund weiter. Erst, wenn ich LrC im TM mit Task beenden  oder den PC herunterfahre, kann ich LrC erneut starten. LrC funktioniert einwand frei.

Mein Laptop Dell  XPS 9500, i7-10750H CPU, 64 GB, NVIDIA, 2TB, Windows 11 home (aktuell)

[Larion476]

Thanks!  It works.

Will we be informed when this bug is fixex?

[ThorstenRu]

- LRc does not terminate correctly (a process consuming memory keeps running)
- masking for motive or persons do not work anymore

- sometimes in this case the prewiev in developing mode crush (you have to restart LR)

- some updates ago also the "lens blur" does not work since some updates ago (before works perfectly)

I'm very, very dissatisfied with the recent updates. The improvements are marginal, and something keeps breaking. The application's stability has deteriorated considerably. Most of the time, the preview pane in the Develop window no longer updates—then the only solution is a restart. Now that doesn't work either. I've already reported this to support, but haven't received any help or confirmation...

@Larion476: "Will we be informed when this bug is fixed?"

When Adobe releases a fix, they will update this thread. So if you continue following it, you'll get an email notification.

[johnrellis]

If you're actively using MID2LR, it could be easier simply to force-quit rather than disable/re-enable it each time. If you're technically minded, you could use a shell script with this line:

killall -9 "Adobe Lightroom Classic"

Crash on quit here too. 

M4 Max, MacOS 15.6, LrC 14.5

[KS-FOTO_Carles]

I am in exactly the same situation.
Lightroom has become an absolutely unstable program.
It has corrupted all my catalogs and backups since February 2025.
I can't open my catalogs because they keep closing.
My entire professional life is currently in jeopardy because of this program's bugs.
It's absolutely unworthy of the Adobe brand.
I'll have to reconsider switching to Capture One, as my friends tell me it's stable and problem-free.

[davidgordon]

I've isolated my LrC fail to quit on a Mac to a plugin Lightroom Super Keys https://www.lrsuperkeys.com/
I see others have the problem but with different plugins.

[photoviator]

Disabling all my plug-ins, Logi Plugin, LogiOptions, AdobeStock, Flikr, Nik 8 HDR Efex and Plugin Parameters (part of Nik8, appears to have removed the issue of being unable to restart Lightroom classic without resorting to terminating the active 'zombie' task in Windows Task Manager. Bit of a bore losing the plug-in functionality, but as a temporary fix it does seem to work. Many thanks.

[HendrickxG]

Hello,

On my lastest MACOS version , lightroom freeze everyting I quit.
If I ask for a backup it does it then freeze, without backup it freeze directly. (Apple balloon spinning forever).
I have to "force quit".
Send report to Apple, but I'm not asket by Lightroom to do so to Adobe.
Regards

@photoviator 

Would it be possible for you to reactivate the plugins one after the other and test with which plugin the problem occurs. I could imagine that not all plugins cause a problem, but only one or two. This would allow you to find out which plugin is causing the problem and then check which functions in Lightroom Classic are faulty.

[photoviator]

Not much time to experiment, too much to do. However:

Tried switching off both Logi options and plugin, Lightroom Classic task peristance after shutting down re-emerged.

Tried with just Logi Plug-in enabled, still a problem.

Tried with just the Logi Plug-in enabled - no persistance, re-start fine.

Can't speak of the other plug-ins on my application but the cause on my windows 11 workstation appears to be associated with the Logi Options task not shutting down on Lightroom Classic closure. Hope helps.

[photoviator]

Typo, The successful third attempt was with only Logi Plugin enabled

[Sandy694]

Based on the above messages it is more than one plugin that can cause the problem. The common denominator seems to be a plugin that interacts with the keyboard or mouse to cause an action.

[mychin_Photo]

I'm also experiencing hangs when trying to quit LrC 14.5 on Mac OS Sequoia 15.6.
I've had no choice but to revert back to LrC 14.4 for now.

I'll wait for an update to LrC 14.5.

[johnrellis]

@Sandy694: "Based on the above messages it is more than one plugin that can cause the problem. The common denominator seems to be a plugin that interacts with the keyboard or mouse to cause an action."

More precisely, I think the issue is with plugins that run a background task within LR that opens a network socket to an external helper program. Plugins that interact with external user-input devices (e.g. Tourbox, Loupedeck. MIDI2LR, LrSuperKeys) typically have this architecture.

Normally, when LR shuts down, it calls the plugin to shutdown its background LR tasks, which in turn shut down the helper program.  That appears to be failing in some way in LR 14.5.  Given the diversity of plugins affected and how many years they've operated without issue, this is certainly a bug in LR rather than the plugins.

[Clifton_Saulnier]

I noticed the same John.  When you exit LrC, the plugin's lua script halts, failing to close the send and receive sockets, which appears to be causing LrC to no longer respond. The current workaround is to first close the helper application (ie: LrSuperKeys). This will close the connected sockets, allowing you to then fully exit LrC.

[Earth Oliver]

I'm finding it hard to believe that this slipped through PR testing...
