I'm having a bug on switch. I've been playing this game a ton since launch, so this may be a progression related bug in some way. Anyways, every time I end the game (either from the menu, or if i die, or if I finish a run), the game will not show my progression statistics, etc, but instead will tell me that the game encountered an error and then crash back to the Switch main menu. This happens every single time. There is no way for me to finish a run.
The run I was on will stay on as an unfinished save. Thus I no longer have any way to make any progression in game because none of my runs ever end.
I don't know what caused this initially, but the game crashes literally every time I play it at the end of a run now.
