This sounds like an incorrect version of angular + flex-layout.

• remove your node-modules directory,
• remove the @angular/flex-layout entry in your package.json
• then run terminal npm i; npm i @angular/flex-layout

Seems there's a (newish) rc-1 out that breaks this whereas it was ok in the -beta.10 pre-release.
maybe this will be fixed in rc-2 ?

I am having this issue with beta.11 but not with beta.10-4905443.
