A small but very welcome feature, but this version is very crashy on Windows 11 - in a way it’s never been for me.

Hi @cadmium48 @ljc576 @susanc82010065,

Sorry for the delayed follow-up on this. Since you originally reported frequent crashes with Lightroom Classic 15.5, could you both let us know whether you’re still experiencing them after updating to the v15.5.1?

If the crashes are still occurring, a few details would help us narrow this down:

What are you usually doing immediately before Lightroom Classic crashes, Develop, masking, switching photos, importing/exporting, or something else?
Does Lightroom Classic close suddenly, freeze, and require you to end the process, or display an error first?
Is there a particular catalog or set of images that makes the crash easier to reproduce?
Please go to Help > System Info > Copy and paste the information here.

If Lightroom Classic displays the Adobe Crash Reporter, please submit the crash report and use the same email address associated with your Community account so we can correlate the reports.

As one targeted test, if the crashes seem to occur primarily while working in Develop, go to Edit > Preferences > Performance, temporarily set Use Graphics Processor to Off, restart Lightroom Classic, and see whether the same workflow remains stable. This isn’t intended as a permanent workaround; it can help determine whether the crashes involve the GPU-accelerated processing path.

If the current release has already resolved the crashes for you, please let us know that as well.

Best,
Anshul Saini

I was getting the crashing mostly right after a big import - so when previews were still likely being generated. After that period, stability improves, but I still a moderate amount of freezes or tools no longer responding after a while (most often masking becoming unusable).

I haven’t had a big import since then to verify is the issue persists in the latest release.

Thanks, that helps narrow this down, @cadmium48. The fact that the crashes were occurring primarily after a large import, while previews were likely still being generated, is particularly useful. The latter freezes and masking becoming unresponsive may or may not be part of the same issue, so I’d like to separate those behaviors before taking this further.

When you next have an opportunity to do a larger import in Lightroom Classic 15.5.1, could you please check the following?

1. After the import, allow preview generation to continue, but don’t do any other editing for a while. Does Lightroom Classic remain stable?

2. On another test/session, while previews are still being generated, work normally in Develop and use masking. Does that make the crash or unresponsive behavior reproducible?

3. When masking becomes unusable, does the rest of Lightroom Classic still respond normally, or does the entire application begin freezing?

4. If you stop/cancel preview generation when the slowdown begins, does responsiveness return?

Please also share Help > System Info > Copy from the affected system and paste it here.

If Lightroom Classic crashes and the Adobe Crash Reporter appears, please submit the report. If it closes without displaying the Crash Reporter, please let me know that as well.

There’s no need to reinstall Lightroom Classic or reset your preferences at this stage. I’m particularly interested in determining whether the problem requires preview generation and editing/masking to occur concurrently, or whether either workflow can trigger the other independently.

Best,
Anshul Saini

Since I downloaded the last Lightroom 15.5.1 update, the program crashes every five or so minutes. I have Intel Core Ultra 7 265KF, 32 GB RAM 16 GB Graphic card.

Same here sort of. App doesn’t crash completely but freezes up/opaque screen. Let it sit for a min or so, then I can resume editing for a few more mins. Not sure of system stats. Not computer savvy.
