I am new to the group but I have been working with spyder and python for 
several years now and never had this issue. I hope this is the right place 
and I am sorry if the solution is found somewhere else. I tried doing some 
searching but couldnt find anything, possibly because I didnt know where to 
start searching.
Problem Description

When my graphics backend is set to inline under Preferences->IPython 
Console->Graphics->Graphics Backend, Then everything works like it should. 
However, if I change the graphics backend to anything other than inline my 
code will not run. The console will show my code is trying to run but will 
act as if it is in a loop. No errors will occur, the console will just sit 
there with nothing happening.

I do not think it is not code related because this happens with ANY script 
I run. Even something as simple as,
import numpy as np
print(np.pi)

I have the same setup (spyder, python, and QT versions) on my home desktop 
(Windows 10, maybe Windows 10 Pro has something to do with it?) and I have 
never had this issue. This problem is occuring on my university lab 
computer. I would like to be able to have the plots be generated with Qt5.
What steps reproduce the problem?
   
   1. Changing the graphics backend to Qt5
   2. Changing the graphics backend to Tnker
