Before deploying my app to the PlayStore i tested it in Release Mode on a physical device (Huawei HUAWEI P9 lite mini, Android 7.0) and it worked fine.
When the app was released, i downloaded and installed it from the PlayStore. Now the app crashes on start after the launchscreen (same device)...
Google provided an crash report with the stacktrace:
