How do you fix Unexpected Error: Invalid filename?

[TornVelocity]

I've been getting this error when trying to export every ust into a wav file, i'm not sure what caused this error but I would really like to get it fixed! Whenever I try to exportthe file, i get the error and then nothing else, I have no idea what to do,,,

Wow, right when I google to look for the answer, I find someone with the same problem I'm having! To be honest, I still don't know the solution, but in the mean time, I converted the ust into a midi file and then reimported it back into utau. It's a pain, you'll have to tune it all over again, but it's all I've come up with so far that's worked.

Where is UTAU located?
Where is the UST file located?
Where are you trying to save the file to?

If any of the folders in the full file path have unusual characters (such as the & symbol) it may be causing issues.

this happened to me and what i did was i went into the project properties and it by it turns out i had to just switch the output file name to something different so hopefully that works for anyone else!
