Win10  
PsychoPy version: 2024.1.3-win64

Hi all,  
I am designing an audio experiment in the builder of PsychoPy in Windows 10 but I face to this error:  
Support for the `sounddevice` audio backend is not available in this session. Please install `psychopy-sounddevice` and restart the session to enable support.  
I installed psychopy-‘sounddevice’ but still I got this error. I uninstalled and installed the PsychoPy two times but it didn’t work.  
I also checked “Preferences” window and the “Audio Library” dropdown menu to see if the newly installed library but it is not in the available options.  
the available options in the “Preferences” for audio driver are: Primary Sound, ASIO, Audigy
