Adding useProguard crashes the app on room connect

Description

Adding useProguard true in app gradle crashes the app.

Steps to Reproduce

Clone this project
Add useProguard true to build.gradle file
run the app in release mode
app crashes

Code

In this project in QuickStartKotlin in file /quickstartKotlin/build.gradle there is this code:

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

If I really want to use proGuard I have to add useProguard true. So the code looks like this:

    buildTypes {
        release {
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

There are the proGuard rules in the project. Not sure if the problem is there.

-keep class tvi.webrtc.** { *; }
-keep class com.twilio.video.** { *; }
-keep class com.twilio.common.** { *; }
-keepattributes InnerClasses

Expected Behavior

App runs the same as without the line of code

Actual Behavior

App crashes when I try to connect to a room.
