Midi keyboard sending midi but no sound

Hi Everyone !

Same old bug but with a twist !

So I opened cantabile which I didn’t opened for a while now, and despite working normaly the last time, I have no sound when using my midi keyboard.

Every midi input are checked, audio is working too, metronome sound is working, I can use my vst using the onscreen keyboard and the sound is working.

midi greenlight working when I push my keys but no sound is coming out of my vst.

I tried it on both my pc and laptop and I still have the same issue.

I looked at my consol logger and this appeared in red in both computers :

00004695 10 ! [27400:0]: Error scanning folder: C:\ProgramData
System.UnauthorizedAccessException: Access to the path ‘C:\ProgramData\Application Data’ is denied.

Is this the source of my problem ? and how can I solve it ?
