[Updated] Adobe Photoshop 23.1 issue with Liquify Tool crashing ('Assertion failed!' error) on Windows to get fixed soon, says support

New updates are being added at the bottom of this story…….

Original story (published on January 24, 2022) follows:

Used by professionals as well as normal users, Adobe Photoshop is the most well-known photo editing software of all time. Developed by Adobe Inc., the raster graphics editor was initially launched in 1990.

The software uses the PSD and PSB file formats with the ability to edit images in multiple layers. While Photoshop has limited support for vector graphics, users can easily expand on the same using community-developed add-ons.


Unsurprisingly, like all software products available in the market, Photoshop users do face some bugs like the issue where the grid was not centered for some and inconsistent keyboard input for dialogs after a recent update.

And it looks like Adobe Photoshop users are facing another problem that is causing the Liquify Tool to crash on Windows. Many say that using the tool several times in one session is causing the app to stop working followed by an ‘Assertion Failed!’ error.

The issue was initially reported back in September of 2020 on Adobe Photoshop 21.2.2.

If the Liquify Tool is used between 475-500 times within the same Photoshop CC 2020 session it gives an Assertion Failed! error and crashes Photoshop. This is very repeatable and happens on every Windows system in my testing. I originally reported this back in version 21.2.2. It is still happening in version 21.2.4. I never received any reply to the prior post so not sure if anyone from Adobe saw it. It is easy to recreate this. Just running a 1 step action with Liquify in a batch process will always crash Photoshop with this error from 475-500 images. This only happens in CC 2020 but not CC 2019.


Adobe had fixed the issue back then with the Photoshop 21.1 update. But fresh reports suggest that the bug is affecting users once again.

Hi Jeff, This issue is back in Photoshop 23.1.0. The issue was fixed from 21.1 – 23.0.2 but is now back again in 23.1.0. It seems that whatever fix was implemented may have been rolled back to the prior state. The issue is exactly the same. It is Windows only. It seems to affect all Windows systems. The error still seems to occur between 475 and 500 image ran through Face Aware Liquify within a given Photoshop session.

Thankfully, Adobe was quick to acknowledge the issue and said that they are working on a fix. However, there is no ETA on when it will be resolved.

I have verified the fix and we are working on getting it thru the pipeline and testing other configurations. Hoping to get this out soon.

We hope the developers deploy the fix as soon as possible so users can continue their work without any interruptions. As always, we will be updating this space when it is fixed so stay tuned.

Update 1 (March 02)

01:11 pm (IST): An Adobe Employee has confirmed that this issue is fixed in the latest Photoshop 23.2 version.
