RemoteControl MIDI at runtime in Windows package

Hello! Is it possible for me to package a windows standalone build that works with the RemoteControl MIDI protocol? I have successfully got my MIDI controls working in Play mode but does not work once I make a windows package - no errors in the output log (Im using Unreal 5.4.4 )
Also to note, I found this https://www.youtube.com/watch?v=jlT-pSWcEr0 where he adds a -RC flag at the end of a shortcut to his windows executeable but that didnt work for me as I’m not using the web server part of RemoteControl API - I just need the MIDI – Is there perhaps a flag I can put on it that will force RC MIDI to work in the build? Or is there another way to make this work? Any info appreciated!!!
