Didn't find class "com.facebook.react.devsupport.DevSupportManagerImpl" on path: DexPathList

I tried to enable proguard on my react native (v61.2) application by setting on app level: build.gradle

minifyEnabled true

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

But i get this error:

Didn't find class "com.facebook.react.devsupport.DevSupportManagerImpl" on path: DexPathList

====

I already have the dependency

implementation 'com.android.support:multidex:1.0.3'

And also have this buildscript dependency already

classpath 'com.android.tools.build:gradle:3.5.0'

Any idea where to look? Stack Trace:
