title: App failed to start because it could not find Qt platform plugin "Windows" in ""
body: <p>I have been bogging my mind on this one for a few days with various versions of python and freeze utilities. 
  Python 3.6, PyQt5 
  I created a script, and am trying to make a standalone .exe 
  However, when running pyinstaller, I get the result I have posted below. I am currently using an Anaconda distribution, so I am not sure if this has anything to do with it. How do I resolve this issue? </p>
  
  <p>I have tried to fix it for several days using different python and pyqt versions, but the short story is that some of the libraries I am using come into conflict in other versions. I am posting this again because nothing else has really worked, and I am on my last straws. </p>
  
  <p>Thanks in advance.
