I'm completly stuck on this. I keep getting error message 

Process finished with exit code -1073741819 (0xC0000005)

I'm using pycharm with pyqt5.6 and qt5.6.2 and the problem started when I upgraded to these versions.
I've tried searching as much as I can, but have not been able to find an answer. Can anyone help please?
I had the same problem today when plotting a simple matrix. For me just changing the Python interpreter helped. I am not sure why, but I could imagine it has something to do with the installed libraries.
