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
