Hi everyone,

Photoshop 2026 (v27.4) on Windows gives me this error constantly when work with curves (i didn't try other tools, so i hope this is the only one): "Impossible to update advanced objects because a program error has occurred (f376f9.749)".

Sorry, my Photoshop is in Italian.

Anyone else seeing f376f9.749 on Windows lately?

Thanks in advance!

While editing in Photoshop 27.4.0 I randomly receive Could not update smart object files because of a program error notifications where I can just force quit Photoshop. And there is no smart object involved - just single layer file with Curves adj. layer.

Very annoying as I lost edits. Modern UI disabled as there are other features that are impacting my workflow. Mac OS Tahoe 26.3.

Adobe please improve quality as lately there are just too many bugs - people dealing with reporting bugs, not creating work - thinking leaving your ecosystem! You can do better! You used to at least.

This sounds like a similar thread,

For now, try disabling Modern Interface in the preferences.

Even with the Modern UI disabled, I still get the error, with both adjustments layers and through the menu.

Could not build the Crop previous because of a program error (f376f9.749).

Seems to happen when I do two consecutive curve adjustments. How can I fix this?

I am having the same issues with curves. I updated photoshop and restarted the computer. I am working on jpgs from a Canon 5D Mark IV. It isn’t happening on all of the images, it seems selective, but I don’t know what the difference between the files would be.

Hi everyone,

Yes; I have the same bug in PS 27.4.0, f376f9.749 when using curves. In my case, I can modify curves without a problem, but when I want to reset it to ‘default’, the error appears.

In this case, the image is already 8bit and has a single background layer. For a new image, same behaviour, only when I click on ‘default’ to reset the curve.

I get the same error on 27.4, Mac Sequoia, RGB images, when trying to adjust a color channel. This was not present in the previous version.
