P: Photoshop app on iPad pro continuing to crash

Despite seeing this thread addressed many months ago in late 2021, the issue of Photoshop's app freezing on iPads continues. There have been several updates with bug fixes and yet this fairly significant issue continues. There is clearly a problem that requires someone to fix as nothing you try works. Resetting all settings in the app, deleting and reinstalling the app, updating the iPad, turning off WiFi, etc.

I cannot use the spot healing tool on a number of imported photos. It seems more of an issue on colour rather than black and white images, but none of these are large files and my iPad has plenty of memory so there should be no issues. After a number of pencil strokes, it simply freezes and the only solution seems to be to close the app, thus losing all edits to date. Very frustrating that as the app evolves with more features, it becomes less usable. I'm sure lots of users prefer to retouch on iPad as the pencil makes it so much faster than working on a laptop. Shame the same issue prevails with no real response almost a year down the line. 

I am running:

iPad pro (11 inch) with OS 15.6

Apple pencil A2051

Any help or information about the progress solving this would be appreciated.
