Spyder doesn't start so this is not possible

I've had a similar issue on Windows 10 today.

After doing Windows 10 updates and updating Python packages, Spyder wouldn't start anymore, instead it was just crashing on startup telling me Python wasn't working anymore.

In the end I decided to cleanly remove my old Anaconda installation and made completely new one, now Spyder is working normally again.

@khalilia2000, this seems to be a problem with Anaconda. We're investigating what its cause is.

Thanks @ccordoba12,
Update: I created another environment with Python 3.5, and everything works. Seems like Python 3.6 is the problem somehow.

Great! Thanks a lot for the feedback!

This was fixed in Anaconda. To get the fix you need to run

conda update python.app

in a terminal.

[gilfoyle1995]

still it crashes

still crashes on Mac after "conda update python.app", that didn't help
