This version of CLI is only compatible with Angular versions

I have Angular CLI: 9.1.12 installed globaly. If I try to run ng serve from my root app it throws the following error:

This version of CLI is only compatible with Angular versions ^8.0.0-beta || >=8.0.0 <9.0.0,
but Angular version 9.1.13 was found instead.


I tried to change the global CLI version but without success.
