Flair 58+ no pressure

Just received my 58+ today. Beans were roasted five days ago. Niche zero set to 10, I tried all the way to 3. I get zero pressure reading. No liquid comes through the portafilter either. When I lift the handle back up, I see some backflow of coffee grinds in the brew chamber.

Dose is 18g. I tried another set of beans and getting the same reaction. I can move the handle with one finger.

Any ideas what I’m missing? Also contacted flair support.
