Uncaught TypeError: Class constructor Platform cannot be invoked without 'new'

I've installed the Angular CDK in order to use PrimeNG's dropdown component but it throws an error.

I've added this in my app.module.ts:

import {DropdownModule} from 'primeng/dropdown';

And installed the Angular CDK by simply typing in the following:

npm install @angular/cdk --save

export class authGuard implements CanActivate {

constructor(private jwtHelper: JwtHelperService){
  }
  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot){
    const token: string | any = localStorage.getItem("accessToken");

    const decodeToken = this.jwtHelper.decodeToken(token);
    const expirationDate = this.jwtHelper.getTokenExpirationDate(token);
    const expired: boolean | any = this.jwtHelper.isTokenExpired(token);

    debugger;
    return true;
  }
  
}

I have this code for using authguard in angular.

@Injectable({ providedIn: 'root' })

When I add this code in up this page my problem is solved.

In case someone has the same issue while trying to implement material design with angular material, rollback both material and cdk packages to an older version with:

npm i @angular/[email protected] @angular/[email protected] --save

I hope someone proposes a better approach that enables using the latest versions.

I had the same issue. Check your cdk version in your package.json

I solved installing an older version of cdk 10:

npm i @angular/[email protected] --save
