Black Screen after changing Map Position in PKHax (Ultra Sun/ Moon)

[levlo_]

Hey, so i was using pkHax for fun and wanted to try out the Map-Position change function, so i changed the X-Coordinate by 1. Then, after Selecting the Save in Game, all i got  was a Black Screen and the Pokemon Center Music without an ability to do anything, not even returning to the Home Menu.

I tried changing the position again (i thought i might have landed in a wall or something) but nothing changed. The Thing is, even after changing the Position to somewhere else and not a Pokemon Center, the Pokemon Center Music kept playing, so i think the game still thinks im in the Pokemon Center when im not, which may cause the Black Screen.

Can someone help out? I really tried everything i could
