Cannot join call in release mode

[gdaino]

It is not possibile to join a call when application is built in release mode

How to reproduce:

• download the example project from the repository;
• run with 'flutter run --release';
• try to join the call tapping on 'join'; -> the call is not joined and the screen goes back to the main page.

Using both a device LG G7 with Android 10, and a Pixel 6 API 33 simulator.
