```

**Troubleshooting Routes**

Tried to remove all minify flags and proguard, still crashing in both release and debug mode.

**How To Reproduce**

1. Run following to build bundle and install to device

```auto
gradlew bundleDebug && \
                                                                 bundletool build-apks --overwrite --local-testing --bundle=./dynamic_sample/build/outputs/bundle/debug/dynamic_sample-debug.aa
b --output=./app-debug.apks && \
                                                                 bundletool install-apks --apks app-debug.apks

```

1. Fill in meeting number and name, click “join meeting”
2. See crash with above error.

Hi @elisa.zoom! Unfortunately yes I still get this error whenever try to join a meeting.

I also tried different versions of the SDK from 5.7.5 to latest. It appears the dynamic\_sample works on APK build but not with AAB build?
