No response after clicking the "run" button in builder, the experiment does not start

Computer: Win10
PsychoPy version : Psychopy 3.7

I have built four psychopy experiment files. Three files worked well, but the last one does not respond when I click on the “run” button. There is no output in the coder view. Does anyone know how to tackle this problem? Does anyone know how to tackle this problem?

Does anyone know how to tackle this problem?

Thanks in advance!

I have solved my problem. That is because the comma I used in the code is not in English. When I changed it in English, it works right again.
