Jupyter Notebook only opens on base environment (Python 3.7, Windows 10) - jupyter-notebook

Question

I'm not sure what changed but similarly to this post:
Jupyter notebook only works in base environment
Jupyter notebook only opens when I activate my base environment, ie:
C:\Users\user\activate base
(base) C:\Users\user\jupyter notebook
This happens on powershell, cmd, and cmder. In the default, unspecified environment, I get this error:
C:\Users\user>jupyter notebook
Traceback (most recent call last):

import _ssl # if we can't import it, let the error propagate
ImportError: DLL load failed: The specified procedure could not be found.
In the default environment, I can call pip commands but I get this error. It seems to be related to my first issue above.
