PsychoPy 3.1.0 - can't open coder view on Windows 10

Hi, I’m trying use PsychoPy version 3.1.0 on a windows 10 laptop. I can’t seem to open the coder view. When I click ’ open cloder view’ a black window pops up very briefly sometimes, not always, then disappears.

I’ve tried the different suggestions here and elsewhere to make the window visible, and I’ve unchecked Hidden files in the AppDat folder. I’m really not sure what else to try.

This is the first time I’ve tried to use PsychoPy. I’ve had some advice from someone but nothing we tried worked.

I did download the latest version of PsychoPy but it wasn’t compatible with te files we are using.

Any help would be much appreciated.

Sorted. I went to the AppData folder > roaming > psychopy3 and deleted the appDatat.cfg file.
Coder view opens and runs experiments now.
