If this template helps then use it. If not then just delete and start from scratch.

**OS** (e.g. Win10):  
**PsychoPy version** (e.g. 1.84.x):  
**Standard Standalone? (y/n)** If not then what?:  
**What are you trying to achieve?:**  
I am trying to run a stroop task in Psychopy  
**What did you try to make it work?:**  
When I pressed run it comes up with an error message

DOES ANYONE KNOW WHAT THIS MEANS AND HOW TO FIX IT!!!  
**What specifically went wrong when you tried that?:**

Include pasted full error message if possible. “That didn’t work” is not enough information.

@Laura_Makin, can you let us know which version of PsychoPy you are using? Some of these issues may have already been fixed in more recent releases.

Can you please copy and paste the whole error message? Also, try going to Preferences in the file menu, and switching the window type to glfw.

I think this issue might be related to driver issues [see link](https://github.com/psychopy/psychopy/issues/1579). Jon mentions that " `Unable to share contexts` is generally a driver issue", and the recommendation is to update your graphics card drivers.

I think it would be best if you google “how to update your graphics card drivers” with the addition of your operation system e.g., windows 10. You might not actually have a separate graphics card, the graphics processor might be built-in, but you can still update the graphics drivers. Alternatively, you could try using the “GLFW” screen type in the Preferences settings in the File menu.
