How did it fail? Did it open app and install assets but then failed to install runtime? If so, check if Out_of_Touch/Game.apk file exists and install it manually, if it doesn’t exist then you have overzealous antivirus deleting game apk before it’s installed. Or did it not open app at all? The error you’re getting is normal, it’s impossbie to build app using new android api because it doesn’t allow file system access at all.
