But, in this thread, you are constantly talking about double tap, which works correctly on my side, even in your project.
And in your scenes it is drawn that I need to use the pinch to zoom gesture.
The patch fixes the behavior when pinch to zoom starts on Canvas.

To make it clear:
I don't need your working project.
I need any temporary project where the problem is happening.

I just tested this and it works correctly:

P.S. I tested the latest version of the asset as I see no point in testing the version of the asset that was released a year and a half ago.
