Just throwing this out here for anyone who had the same problem as me. The BuildBackup program requires .NET 2.2.0 x64 (Not x86) to run, and if you're like me you may not have the x64 version, so make sure to get that one in particular if the program is failing to launch.
Also consider adding a Pause to the last line of your .bat file like this;
dotnet BuildBackup.dll forcebuild wow 3b0517b51edbe0b96f6ac5ea7eaaed38 da4896ce91922122bc0a2371ee114423
Pause
that way you can see what error code the program is throwing!
