I am using Spyder through the WinPython-64bit-3.6.3.0Qt5 distribution on my Windows 7 Laptop. To add a third screen to my Laptop I started using a USB 3.0 Docking Station. After Installing the drivers Spyder won't launch, neither will the WinPython Control Panel. 
These are the drivers I installed:
DisplayLink Graphics Driver Version: 8.0.762.0
DisplayLink Ethernet Driver Version: 8.0.403.0
DisplayLink Audio Driver Version:    8.0.745.0
Uninstalling the drivers fixes the problem, but my question is if this is a known issue and if there is a way to use both Spyder and the Docking Station.
So far I have tried updating PyQt5, which had no effect.
This is not really a solution to the problem, but it's how I am able to use Spyder again.
I downloaded and installed the latest Anaconda (Version 5.0.1) distribution. I am able to launch Spyder, which is included in that distribution, even with the docking station drivers still installed.
