I was able to resolve my issue by completely uninstalling/removing nodejs and then reinstalling using conda.

If anyone has a better answer to it you may share here. Thank you. https://stackoverflow.com/questions/59386899/language-server-spec-finder-errors-when-launching-jupyter-lab/59712389#59712389
