Psychopy Test Shows Stimulus On Apple Not Windows Devices

PsychoPy version 2023.1.2
**Standard Standalone (Y)
What are you trying to achieve?: = Trying to get N-Back (1Back, 2Back, 3Back) Tests to function on windows computers, currently the stimulus is not appearing and the screen just displays a crosshair where it would be. I beieve this could be a font issue as the stimuli are letters?

**What did you try to make it work?: I have just noticed that every apple computer this test is run on, the test runs fine. When it is run on any windows computers, there is no stiumulus and the screen shows are crosshair.

What specifically went wrong when you tried that?:
Include pasted full error message if possible. Stimulus is not shown and the screen is blank with crosshair where the stimulus should be.
