Error message in my Drag and drop experiment

Builder
1

Hi I’m new to Psychopy3/coding and I am trying to create a drag and drop based experiment which requires participants to place pictures containing different types of people around the screen.

I have created an experiment in builder off of the drag and drop demo however every time i attempt to run it i get a blank grey screen and then it quits out.
the message warning:matplotlib.font_manager:findfont: font family [ ’ ’ ] not found. Falling back to DejaVu sans.
Is then shown. Does anyone know how to rectify this error or what im doing wrong?

I think that is just a warning. If the drag and drop demo in Builder works, but your changes do not, it may be something to do with how your experiment is set up.
