Angular 9 Ivy - Generic type 'ɵɵFactoryDef' requires 2 type argument(s)
Fortunately, Angular 9.1 has been released and the problem solved. After upgrading to 9.1 (by running ng update @angular/cli @angular/core) I deleted my node_modules and reinstall it again. Then I upgraded my typescript from 3.7.5 to 3.8.3. Now the ngcc is working fine and I have no errors after building.
