                    //web.BreakRoleInheritance(true, true);

                    this.context.Load(web);

Hi @John Mphahlele

Per my test, I can run the code and add permission to user successfully with your code.

My Token have full control with site. Please check your permission of your azure ad app only.

You can grant Sites.FullControl.All in API permissions
