vertex AI Workbench is hanging with error "Opening notebook with JupyterLab" for more than a day

[joeeapen]

I am trying to follow instructions in https://cloud.google.com/vertex-ai/docs/tutorials/jupyter-notebooks (vertex AI Jupyter Notebooks tutorials). Steps done

1. For the first notebook "Text Classification model" I have clicked on "Vertex AI Workbench". It takes me to GCP console & workbench.

2. I am supposed to click on the "Create" button, which I did.

3. THen the message "Opening notebook with JupyterLab" will come. But it is there for past 1 day, and still it hasn't finished creating. So I canceled the same. I tried once more the same thing happens. Not sure why?

I have screen shots, but can't see anywhere to attach.

Have anyone tried this tutorial, especially in workbench? 

Thanks,
