Stimuli not showing up online

Hi,

My stimuli component shows up locally using psychopy but fails to show up online.
In order to ensure that this had nothing to do with my actual experiment, I also pulled in an experiment that was part of prewritten psychopy build/demo. It also works locally but does not show the stimuli online.

demo:

When running online, I get a screen saying ‘initializing experiment …’ and it remains stuck there. If I remove the stimuli, the rest of the experiment works online.

What could be wrong? I don’t have any import statements. The demo example should atleast have worked online but doesn’t either.

thanks

OS (e.g. Win10): mac sierra
PsychoPy version (e.g. 1.84.x): 2020.2.3
Standard Standalone? (y/n) If not then what?: scratch build
