Anaconda/Spyder sudden crash and startup error: Socket issue and/or ImportError

I have been using Anaconda distribution with Spyder IDE for some months without any problem. This morning, my system froze while a Python program was running and I had to restart. (Cause of freezing is unknown, but not program-related, since I checked it on multiple other systems.)

Since then, I am unable to start Spyder.

(1) On opening Spyder directly, I get:

"An error occured while creating a socket needed by Spyder".

(2)On opening through Anaconda prompt I get:

"ImportError: cannot import name '_overlapped'"

and

"OSError: [WinError 10022] An invalid argument was supplied" The full output is attached below.

(3) Anaconda Navigator freezes and closes on opening

I have tried the following steps without success:

(1) Restarting Spyder, restarting system.

(2) Resetting Spyder settings and restarting system.

(3) Resetting network settings using "netsh winsock reset"

I will be very grateful for any direction and suggestions to solve this problem and get Spyder running again.

(Spyder maintainer here) I'd say the freeze you mention corrupted your H:\ partition, so I think you need to reinstall Anaconda to fix this problem.

Is this on Windows or are you using Wine?

In any case, try the following: 1) remove old Python and old virtual environment using 

conda list

to see what environments you already have then

deactivate

followed by 

conda remove --name myenv --all

2) install new Python version (64 bit would be recommended) https://www.python.org/getit/

3) add new env

conda create -n myenv python=3.6.5 #version of Python you installed

More conda commands here: https://conda.io/docs/user-guide/tasks/manage-environments.html
