Thanks for the log. I think the reason for the error may be that your built banks output directory is set to S://Game (Perforce)/Content/FMOD/Desktop, which is outside the p4 workspace. Try setting it to the default (no path) or specifically to the correct path in the p4 workspace, and see whether that resolves the issue.
Side note: since this is a public-facing forum, we’ve gone ahead and removed some personal details (IP address) from your log for you - in future, you may want to double check for this.
