why login not working after form submission ?

login.ts :
`async onSubmit(): Promise {
this.email = true;
this.pwd = true;
this.mailform = true;
this.isLoginInProgress.set(true);

this._authService .login(this.form.controls.email.value.trim(), this.form.controls.password.value.trim()) .pipe( catchError((error: HttpErrorResponse) => { this.handleAuthError(error); return of(error); }), tap(response => this._handleLogin(response)), finalize(() => this.isLoginInProgress.set(false)) ) .subscribe({ error: (error) => { console.error('Login error:', error); } });

}

private _handleLogin(response: any): void {
if (!response?.user) return;
this.login = true;
const accessToken = response.user.accessToken;
const user_uid = response.user.uid;
localStorage.setItem(‘accessToken’, accessToken);
localStorage.setItem(‘user_uid’, user_uid);
window.location.reload();
this._router.navigateByUrl(‘/dashboard’);

}

handleAuthError(err: HttpErrorResponse): void {
if (!err.error.code) return;

this.authError.set(true);
this.form.valueChanges .pipe( take(1), tap(() => this.authError.set(true)) ) .subscribe();

}
`

login.html :
<form [formGroup]="form" (ngSubmit)="onSubmit()" class="form-detail">
</form>
authservice.ts :
`login(email: string, password: string): Observable {
console.log(‘Logging in user:’, email);
const promise = signInWithEmailAndPassword(this.firebaseAuth, email, password)
.then(response => {
console.log(‘Login successful:’, response);
return response;
})
.catch(error => {
console.error(‘Login error:’, error);
throw error;
});

return from(promise);

}
