Can't open jupyter notebook due to jsonschema [already tried other solutions on stackoverflow]

Question

I am using python 3.8 on Windows 10 machine. I normally use VS Code and ipynb (without anaconda) inside it and everything was running smoothly A couple days ago, I started to het the following error:

    Traceback (most recent call last):
  File "c:\users\kshit\onedrive - university of waterloo\programming\python\installation\lib\site-packages\nbformat\validator.py", line 12, in <module>
    from jsonschema import ValidationError
  File "c:\users\kshit\onedrive - university of waterloo\programming\python\installation\lib\site-packages\jsonschema\__init__.py", line 34, in <module>
    __version__ = metadata.version("jsonschema")
  File "c:\users\kshit\onedrive - university of waterloo\programming\python\installation\lib\importlib\metadata.py", line 531, in version
    return distribution(distribution_name).version
  File "c:\users\kshit\onedrive - university of waterloo\programming\python\installation\lib\importlib\metadata.py", line 504, in distribution
    return Distribution.from_name(distribution_name)

    raise PackageNotFoundError(name)
importlib.metadata.PackageNotFoundError: jsonschema

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "c:\users\kshit\onedrive - university of waterloo\programming\python\installation\lib\runpy.py", line 193, in _run_module_as_main

    raise ImportError(str(e) + verbose_msg)
ImportError: jsonschema

    Jupyter notebook format depends on the jsonschema package:

        https://pypi.python.org/pypi/jsonschema

    Please install it first.

I tried to search for solutions on stackoverflow: Can't use Jupyter Notebook: jsonschema apparently missing

But none of the answers there worked for me.

I tried upgrading jsonschema, jupyter and pip itself several times but to no avail. Tried running it in Pycharm too, And I believe I have not changed anything in my python environment.

Any help is greatly appreciated.

Thanks, Kshitij.

You shouldn't use pip install --upgrade pip to upgrade pip - it will throw some errors. You should do so from the website. A temporary solution to jupyter notebook is Google Colab - colab.research.withgoogle.com. It also uses .ipynb. Hope this helps!
