Oh man, The window was hiding the hypercon config button! It was filling my laptop screen so never even thought to maximize it haha.
According to the logs it detected the madVR renderer (by its setting) which is odd if it works with 1.17.0.0 as that didn't have support for it, are you using any custom Mediaportal builds (or used one in the past)?
If this was the case attached new build which has an additional check to handle this and should sort it out
