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.
@Damon D Bell since you are on PreRelease you may get a chance to put it thru it's paces as well before it goes public. Watch for an email as I will update the ticket you filed when it is ready to test.
