Update:
That player has concluded that reducing the frame rate has resolved the crashing issues for them.
The kingdom I am in also picked up a new player over the weekend who was also having the same issue and also reports that reducing the frame rate resolved the crashing for them as well. 
That’s wonderful to hear!
We still have some more work for those like myself with a Pixel 6, but hopefully that will also be resolved soon!
Similar somewhat,
Have you also encountered visual glitches where when playing on 60 FPS, the game loses visual sync for a moment and does some slightly odd things like watching an enemy be defeated before the board resolves itself visually? 99+% sure nothing mechanically is wrong behind the scenes, but just the odd occasional momentary visual glitch of combat resolving out of order (the correct combat result is being generated when the visual glitch occurs, and the visual glitch doesn’t carry over between battles).
I have not had that, but have you had other players with a Pixel report that along with the crashing?
I so rarely play on my phone, seeing as I am at my PC for work
Just a personal observation of mine.
Can’t find any way to duplicate the issue reliably and doesn’t cause any crashes and is infrequent, so I figured it is possible that the observation might be related to the 60 FPS issue in this thread.
