How to make vscode work with playsound module?

I have this very simple test code:

from playsound import playsound

playsound('alarmsound.wav')

alarmsound.wav is a file in the same directory. when I run it in a terminal, it works fine. but when I run it in VSCode, it blows up with the following message:

Traceback (most recent call last):
  File "c:/Users/Luca/Desktop/Python/own/playaudio.py", line 3, in <module>
    playsound('alarmsound.wav')
  File "C:\Users\Luca\AppData\Local\Programs\Python\Python38-32\lib\site-packages\playsound.py", line 35, in _playsoundWin
    winCommand('open "' + sound + '" alias', alias)
  File "C:\Users\Luca\AppData\Local\Programs\Python\Python38-32\lib\site-packages\playsound.py", line 31, in winCommand
    raise PlaysoundException(exceptionMessage)
playsound.PlaysoundException:
    Error 275 for command:
        open "alarmsound.wav" alias playsound_0.7197283376226026
    Cannot find the specified file.  Make sure the path and filename are correct.

It used to work in vscode before, now suddenly it blows up. what could be wrong?
