Monogame with Nez black screen issue

So, I just started out using Monogame with NEZ, but I get a black screen when I run my game

I’m currently following this guide https://github.com/prime31/Nez/wiki/1.-Getting-Started

I’ve tried referencing NEZ from a git clone, but that didn’t work
If I resize the screen it flickers the cornflower blue color
can somebody help me with this

I’m using the MonoGame Cross Platform Desktop Project template
