无法使用意图更改片段内的活动

我正试图创建一个注销按钮，将我发送回登录页面活动，但出现了一个错误，我不确定如何修复。错误发生在"Profile_FFragment.this，LoginPage.class"。

这是的源代码

public class Profile_Fragment extends Fragment {
Button btnLogout;
FirebaseAuth mFirebaseAuth;
private FirebaseAuth.AuthStateListener mAuthStateListener

StorageReference storageReference;
private static final int IMAGE_REQUEST = 1;
private Uri imageUri;
private StorageTask uploadTask;

@Nullable
@Override
//inflate the fragment
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
btnLogout = getView().findViewById(R.id.SignOutButton);
btnLogout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
FirebaseAuth.getInstance().signOut();
Intent intToMain = new Intent(Profile_Fragment.this, LoginPage.class);
startActivity(intToMain);
}
});

return inflater.inflate(R.layout.fragment_profile, container, false);
}
}
