This example crashes on load
Running the latest 1.5.0 kotlin compiler and Canary 2021.1.1 Bumblebee on the Composable template. I can't get this to load. The app crashes immediately upon starting up. Also tried to switch to new lifecycle dependencies and it made no difference. Looks like it never completes the "viewModel.setUserId("1")" line. Is there a new update to ViewModels that breaks this example?
