If the crash occurs when you first start, the issue could be due to using an older Renpy runtime because older Renpy versions (prior to 8.10) do not support match statements.
Apparently, the most common way this occurs is when using JoiPlay or other emulators to play the PC version on Android. If this is the case, you'll need to ensure the emulator is using a plugin that uses Renpy 8.1 or later to avoid the crash.
Thanks so much for reporting this. I got a similar report related to the battle_manger.perform actions label, so I think python is confusing the label name with a similar function name and causing the error. Working on playtesting an updated version that I can hopefully release this weekend.
