New Arena Bug

I have encountered bug in the current arena event Boomberry tournament where at a certain point during matches the game crashes and exits me to my home screen.  It happens every time the same time I play: regardless of which plants I have or whether or not I have planted, it's at the moment when the first Zombie King is about to spawn at about 2:40.  

Not sure if EA is aware of this, but it's made the arena unplayable as as soon as I open the game it has consumed the gauntlet and I get no points.  Additionally I have tried to clear the cache and restart my phone etc but nothing has worked.
