Hi Guilherme Veiga
The Make It Native app crash you’re seeing won’t show up in the Mendix Runtime logs because it’s happening inside the native client itself. To debug, you need to enable native app logging or check the device‑side logs (Android Logcat / iOS Xcode console).
I would suggest you to build your own dev app instead of using mendix make it native, Kindly follow the mendix doc to build a native app.
