❔ Winforms one window app with navigation between windows

Hello there, I'm trying to implement a one window winforms app with navigation between the various forms using a dictionary and abit of manipulation with Dispose and Application.Run() Here is a snippet of the running loop code

while (navigatedForm != "quitting")
            {
                switch (navigatedForm)
                {
                    case "LoginForm":
                        allForms[navigatedForm] = new LoginForm();
                        break;
                    case "RegisterForm":
                        allForms[navigatedForm] = new RegisterForm();
                        break;
                    //case "EmailVerificationForm":
                    //    allForms[navigatedForm] = new EmailVerificationForm();
                    //    break;
                    case "MainMenuForm":
                        allForms[navigatedForm] = new MainMenuForm();
                        break;


                    default:
                        break;
                }

                try
                {
                    Application.Run(allForms[navigatedForm]);
                }
                catch (Exception ex)
                {

                    DisplayTestWindow(ex.Message, ex.Source, 1);
                    
                }
                Application.Exit();
                
            }

while (navigatedForm != "quitting")
            {
                switch (navigatedForm)
                {
                    case "LoginForm":
                        allForms[navigatedForm] = new LoginForm();
                        break;
                    case "RegisterForm":
                        allForms[navigatedForm] = new RegisterForm();
                        break;
                    //case "EmailVerificationForm":
                    //    allForms[navigatedForm] = new EmailVerificationForm();
                    //    break;
                    case "MainMenuForm":
                        allForms[navigatedForm] = new MainMenuForm();
                        break;


                    default:
                        break;
                }

                try
                {
                    Application.Run(allForms[navigatedForm]);
                }
                catch (Exception ex)
                {

                    DisplayTestWindow(ex.Message, ex.Source, 1);
                    
                }
                Application.Exit();
                
            }

In each form when the user goes to the next, I call Dispose(). In terms of memory, when I tested going back and forth on 2 forms, the Task Manager shown that the memory didn't significantly bypassed the 30-50 MB threshold and at one point dropped to the starting 18 MB. My question is, Is this way hacky and unsafe or it's fine?
