Pokemon Ultra Sun - Crash on Route 11

I have this problem. My game always crashes on Route 11, the moment Rotom gives you the Roto Prize Money boost. I tried to give all the Prize Money boosts to my pokemon in the PC, but he still gives me one and the game crashes.
Maybe it’s noteworthy that it never crashed before, in any game, only when Rotom gives you his boosts.

Fast help on that topic would be appreciated.
