This looks to be the build report for Vortex. It's probably failing because it doesn't exist when running from Mod Organizer.

Mistaken assumption that File.Delete would have an implicit "if exists". It doesn't.

Misinterpreted the original log. It's not that the file doesn't exist, and File.Delete does handle that. The problem is that the setting (BuildReportPath) is empty. This should never be the case and I'm looking into why.
