ModuleNotFoundError: No module named ‘pyrsistent’
This means your environment is missing packages. It looks like the update. This isn’t related to jupyter, but your Python installation in general. You can try conda update or conda install to ad the missing packages (the error suggests that pyrsistent is missing and required, so conda install pyrsistent may solve your problem, but it may only be one package of many that’s missing). You can also try pip check to check for unmet dependencies.
In general, this is a question for Anaconda Support, not Jupyter.
