got the same errors today using angular cli 7

[naveedahmed1]

I generated a new project with Angular CLI 7 RC3 using below command:

ng new temp --experimental-ivy

Now when I try ng serve, the app compiles successfully but when I run it in browser its broken and shows below error in console:

Uncaught Error: ASSERTION ERROR: Type passed in is not ComponentType, it does not have 'ngComponentDef' property.

I also tried ng serve --aot but it throws below error:
