Can't run nor debug project but gradle build+install work

Question

After update to Android studio 3.6 Canary11 (macOS) I cannot run nor run Debug variants of my project (Release variants working fine).

When I try to run the project

Answer 1

I had a similar issue with Android Studio 3.6 Canary 12 on Mac, I could build different build variants but had this error when I tried to Generate a signed apk:

Entry name 'kotlin/collections/MapWithDefault.kotlin_metadata' collided

I had to delete the .build folder as well as the folders where I build my build variant.
