Spyder on Windows crashes when entering "help("modules")"

3

So, it seems my computer's python (Both python 2 and 3) configuration is screwed up in some clandestine way. Originally, I uninstalled Enthought Canopy (Windows 10 64 bit) using "Apps & Features" instead of "Uninstall a Program". Once running spyder through Anaconda I ran "help("modules")" in the ipython window and received the following error:

C:\Users\Jacob\Anaconda3\lib\site-packages\IPython\kernel\__init__.py:13:
ShimWarning: The `IPython.kernel` package has been deprecated. You should
import from ipykernel or jupyter_client instead.
"You should import from ipykernel or jupyter_client instead.", ShimWarning)

Followed by several similar errors for different files, seemingly random.

After these errors seem to overwhelm the system it erases the previous log and replaces it with a red box titled: "An error occurred while starting the kernel"

Windows fatal exception: access violation

I've tried:

spyder --reset

As well as uninstalling every version of python on my computer, along with every directory folder and file I could find. After reinstallation, the same problem occurs.

My current sys.path is:

['',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages\\spyder\\utils\\site',
'C:\\ProgramData\\Anaconda2\\Lib\\site-packages',
'C:\\ProgramData\\Anaconda2\\Lib',
'C:\\Users\\Jacob\\Anaconda3\\python36.zip',
'C:\\Users\\Jacob\\Anaconda3\\DLLs',
'C:\\Users\\Jacob\\Anaconda3\\lib',
'C:\\Users\\Jacob\\Anaconda3',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages\\Sphinx-1.5.1-py3.6.egg',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages\\win32',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages\\win32\\lib',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages\\Pythonwin',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages\\setuptools-27.2.0-py3.6.egg',
'C:\\Users\\Jacob\\Anaconda3\\lib\\site-packages\\IPython\\extensions',
'C:\\Users\\Jacob\\.ipython']

I haven't been able to find this specific error anywhere I've looked on the web, so hopefully someone here has a clue where the problem is.

python
windows
anaconda
access-violation
spyder

This looks like the issue reported at https://github.com/spyder-ide/spyder/issues/4014 . In that case, the solution is to upgrade qtawesome (a dependency of spyder) to version 0.4.4 or higher. If you installed using Anaconda, the command is: conda upgrade qtawesome.
