python - Problem when using azure cognitive services (.dll file not found) - Stack Overflow

I have an app made with flask that is working fine on my machine. I'm trying to move it to a server in order to make in accessible to some people. I've installed all the packages and check that everything has the same version as on my local machine.

Everything seems fine but when I try to run the app, it throws this error:

C:\Users\Sparapan.F\Desktop\Scripts\Trascrittore\Tutto\trasc_env\Lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

FileNotFoundError: Could not find module 'C:\Users\Sparapan.F\Desktop\Scripts\Trascrittore\Tutto\trasc_env\Lib\site-packages\azure\cognitiveservices\speech\Microsoft.CognitiveServices.Speech.core.dll' (or
one of its dependencies). Try using the full path with constructor syntax.

The missing file is actually present in the specified folder so I don't know what to do. Already tried: uninstall and re-install cognitive services check python and system versions (both 64 bit) restart the system
