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?
Same problem,  this resolved in my case:

try run from command line (no pycharm), it works ( exception only in debug )
closed pycharm
deleted ".idea" folder inside project path
opened pycharm
reconfigure python runtime version and command line parameter
debug works
Process finished with exit code -1073741819 (0xC0000005) Pycharm
