Variable Inspector clears all variables and stops recording new ones
I find that my Variable Inspector cleared all variables and stopped recording new variables. I do not know whether I pressed anything wrong. It works well on a newly created notebook.
The problem stated above was fixed by restarting Kernel (or something else that I did not notice). But today, I come across another similar but more serious problem after I installed the xeus-python by pip install xeus-python. The Variable Inspector cleared all variables, and it got stuck on "Restarting kernel". Uninstalling xeus-python and re-installing Varaible Inspector can not fix the problem.
I have had an adjacent issue to this. I was experimenting around with what variables could be inspected when installing the extension. Everything was working well until I created a dictionary in one file. The variable inspector broke on this and would not stop inspecting the kernel of the notebook with the dictionary.
Since then, whenever I have restarted kernels for any notebook the variable inspector would display variables for the previously shut down kernel and the log, in debug mode, would output errors that I do not understand. It would freeze the variables it had already observed in place and switching between notebooks, running code, anything I could think of would not make a change. The following is an example log:

The output indicating when I restarted the console is in the above, but here it is isolated for clarity:

I am running JupyterLab on windows. The version of JupyterLab is 3.6.4 and the version of Variable Inspector is 3.0.9.
