Thank you for the report!
In what part dos it happen?
In case the game is not opening, consider clearing all game cache, uninstalling, and installing it again to see if it works.
This is when you start the game through the apk.
A friend managed to generate the apk through the PC game and said it was because Live2D was not enabled in the SDK when it was generated. He said he used CubismSdkForNative-4-r.7 in his sdk and with that the apk started working normally here.
I apologize in advance for asking my friend to make the apk without permission.
I apologize for any typing errors as I use Google Translate from PT-BR to English.
