I'm new to `django` and using the `anaconda cloud environment`. Its been working well for 3 months plus but as of 7-24-2018 it is just stop to launch the navigator or open through cmd. I can't manage environments or install packages. Using the `anaconda prompt` also gives me the same error upon launching. It started when I wanted to install `django-Oscar`, but not having its dependencies I was forced to install the packages manually which in turn needed `cytoolz` that needs `Microsoft Visual C++` build tools which I got to install as well but the error persists. Please help me!

Copy/Paste of CMD Traceback:

I've just found out that I cant even use any conda commands except the : >conda --version< command only.
Please help me resolve this issue without uninstalling then reinstalling anaconda completely
