Greetings, I do have exatly the same error.  Jupytar-lab 2.2.6 here installed de package as it is explained in installation page: - jupyter labextension install @jupyter-widgets/jupyterlab-manager -...

I had the same problem, when one queries the DataBase to check active connections, it can be seen that the connections is gathering there, and not really being closed. So...

I was to request this feature, but I thought that someone would already remember this, no one but Alex himself :) This would be a great enhancement!! :)
