Ошибка при запуске ноутбука Jupyter

Question

Я установил Anaconda, и при попытке запустить ноутбук jupyter выдает ошибку:

Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\Scripts\jupyter-notebook-script.py", line 10, in

mod = __import__(name, fromlist=['default_handlers'])
ModuleNotFoundError: No module named 'notebook.tree'

Я попытался переустановить Anaconda как для одного, так и для нескольких пользователей.
