Error on Startup on ver 2.2.0

This error appears when launching 2.2.0

Here is the fixed version, it shouldnt crash at all now.
When a sound was missing, I made it to play a blank dummy file to prevent crash from missing sound.
But the dummy file disappeared for some reason so it crashes

I apologize for the issue
