Sound files error please help! :)

Hello everyone :grinning::grinning:!

I need some help…

My experiment involves presenting sound stimuli, then after each one the participant identifying the sound and rating the sound on a quality.

However halfway through, the sounds stop playing, and a Windows error message sounds, which also sounds when ever you press a key response.

This is the output:
psychopyerror

All the sound files are in the same folder as the PsychoPy folder, and all are correctly written in my excel file.
