dagster

Facing an issue, launching `dagster dev` pointing to a `workspace.yaml` with two code locations (e.g two local modules) does not work, dagster freezes up on "Launching Dagster Services".

If I comment out one of the two modules, dagster launches properly, and if reintroduce the module after dagster is running, and press the reload button on the UI, everything works fine.

Hi Andrea, can you check what version of the grpcio package you have installed?

Thanks Daniel for following up! 
grpcio==1.48.0
grpcio-health-checking==1.43.0

And immediately after googling dagster found the github issue that pointed to the dead locks :D

Seems upgrading is not possible as dagster does not support beyond 1.48.0, but downgrading to 1.47 solved my problem!
