I'm trying to start up the Jupyter Notebook application and it is not working at all.
I've tried opening it from the windows menu, a command prompt window opens up and closes.
I also tried running it from the anaconda command prompt and it gives me the following error:

Please help!!! I am unable to use Jupyter Lab anymore and it is extremly problematic for me!
Thank You.
From my point of view, it may be faster, and easier is to reinstall Jupyter Lab (maybe create a new conda environment if needed).
One more thing, you might consider backing up your conda environment when everything is smooth:

You just need to do this step
pip uninstall pyzmq
and after that
pip install pyzmq
go back to your anaconda-navigator and try to launch Jupyter lab and it'll work fine
