Problems syncing with Pavlovia

I can’t sync my PsychoPy experiment to Pavlovia.
Can someone please explain this issue to me so I can fix it?
This error seems to exist only with my PC. I tried with another PC and it works.

Here below the ERROR when I try to sync my PsychoPy experiment to Pavlovia:

"PSYCHOPY3 ERROR
PsychoPy encountered an unhandled internal error!

The above exception was the direct cause of the following exception:
