Could you please help me? I'm having an issue with an error in Unity.

I'm getting a 'build failed' error message when I try to publish my avatar in Unity. I've tried everything I can think of, but I can't seem to resolve it.

error :

I've had this error before, and it seems to just be a unity bug. However, are there any other RED errors in your console? Maybe even yellow warnings?
