wglMakeCurrent WindowsError: exception: access violation reading 0x000000

Hi guys,
I have several psychopy (1.90 standalone, windows10) experiments up and running fine. Since I’ve been trying to add elemnts to one of them I’ve been experiencing problems. Right now none of my (formerly working) experiments work; Python simply crashes. Any ideas? Help much appreciated!

This isn’t an issue with Python3. It’s almost certainly to do with your graphics drivers. See previous response:

Thank you Jon,

since I’m using Psychopy 3.03 I’m not experiencing any problems anymore!

That’s great (although i actually don’t think we’ve changed anything here!)

The problem reoccured and so far I didn’t find a driver that could solve the problem. Could it als be to do with the fact that I’m running on win64 rather than win32?
Anyone else experiencing this problem?
