Problem with "Could not connect to the Gradle daemon" and IP address when running a Flutter app

Question

I'm trying to launch the Flutter app (Flutter's version 2.10.3) on a Mac M1.

I made the next updates to the file android/app/build.gradle:

Some of my Android settings:

• compileSdkVersion from 28 to 32
• targetSdkVersion from 28 to 32
• android/build.gradle: ext.kotlin_version = '1.5.31'
• android/gradle/wrapper/gradle-wrapper.properties: distributionUrl=https\://services.gradle.org/distributions/gradle-6.9-all.zip

I runned the app on an emulator API 32 (Android 12L), but the Gradle throwed an exception.

The log:

...
Launching lib/main.dart on sdk gphone64 arm64 in debug mode...

FAILURE: Build failed with an exception.

* What went wrong:
Could not connect to the Gradle daemon.

The problem disappears when I change the settings of the ProtonVPN to a less secure configuration. There's a feature that is Kill Switch that protects your IP address in case you unexpectedly lose the connection to a ProtonVPN server. [...] This means that even though you can’t use the Internet until ProtonVPN reconnects, your IP address and DNS queries are safe from being exposed.
