Second Jupyter cell takes forever to execute

What I did:

  • create a new folder
  • create an empty Project.toml
  • create a new notebook
  • open a console for that notebook and run ]add CSV,DataFrames
  • now in the notebook execute @time using CSV,DataFrames - takes about 8 seconds
  • go to the next cell and excetute @time a=3 - takes forever(no result cell still running)

I am using the 1.3-rc4 kernel as this version can handle the Project.toml on a network drive on windows. Jupyterlab is at version 1.1.3.

Packages like Core, LinearAlgebra or self written packages don’t have an impact.

It works with 1.0.5.
