Awesome, is it the wave 'crash' image, or the gigant wave that is animated that crash it in your opinion? Will take a look anyway, but more precision could help if you have an idea!
It's the "collision" animation itself (so your second guess, I think)
Here, I resort to doing this: save the game on the last stable point (the screenshot, with the last chatbox before triggering the Wave) and then... Keep trying/crashing until I successfully reach the next scene (the character drowning)
Sometimes it crashes immediately as soon as the wave approaches, other times when the wave covers like... half/all of the screen?
Both, much more frequent on Android:
The Wave only crashed 2~3 times on the PC and that was it.
Meanwhile on Android, the Wave crashed 9~11 and one more time during the dream with the Sister(?)
Note: I write "Sister(?)" because I'm not really sure if I'm dreaming with her. If it's actually her that's talking with me/my character :P
