App can't launch with proguard-android-optimize.txt, but works with proguard-android.txt

What happened?

Hi, when using the default ProGuard rules file (proguard-android-optimize.txt), I receive the following error

 Failed to run application on the device

    HINT: Most likely, your tests have timed out and called detox.cleanup() while it was waiting for "ready" message (over WebSocket) from the instrumentation process.

    > 21 |   await device.launchApp(launchArgs);

Here's my build.gradle release config. It works with proguard-android.txt, but not with proguard-android-optimize.txt

release {
            signingConfig signingConfigs.release
            minifyEnabled true
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
            proguardFile "${rootProject.projectDir}/../node_modules/detox/android/detox/proguard-rules-app.pro"

            firebaseCrashlytics {
                mappingFileUploadEnabled true
            }
        }

I'm wondering if this problem is specific to my environment. Is anyone able to get it working with the optimize version?

Perhaps a warning could be added to the Android guide so people know to use proguard-android.txt.

Was it tested on latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

In what environment did this happen?

Detox version: ^20.25.5
React Native version: 0.75.2
Node version: v20.17.0
