vatSys crash on profile launch

Hello, anyone have any idea how to fix this erorr when trying to load a vatSys profile? To provide more reference, I use voicemeeter banana, and as far as I'm aware I have had no prior issues or any audio devices setup. I had also uninstalled and reinstalled it once, and the error presists. 

Object reference not set to an instance of an object.

Hi Ryan

I'm not sure what banana does, but yes this error is likely coming from a device you have connected (could be an output too). Try removing devices one by one until vatSys boots. You may also try deleting %LocalAppData%\Sawbe.com to erase the saved user information
