Android App - using multidex and firebase - app crashes - firebase

Question

In my app I'm using a barcode reader from play-services-vision. Because of added firebase messages dependencies, I had to add multidex suppport. But as soon as I add the firebase dependencies, the app crashes on my Galaxy S8 (Andriod 9). When I run the app and like to start the barcode functionality, the ap crashes with a class not found exception:
I did the steps to add multidex and firebase dependency adding step by step, as soon as I add firebase dependency - the crash occurs in the app.
exception:
