Sucsess response to PowerApps not working

[marppp]

I created a flow that creates an excel file by using a stored procedure. This always runs sucsessfully in power automate, but I want power apps to send the user to a success screen when the flow has run succsessfully. No matter what I do, it won't do it and I don't know what I am doing wrong. I have this same code on other flows and it works there... 

Does anyone have any idea why it wont send the user to a success screen?

This is my flow:

And this is my code in power apps: 

If(getTeamUpdatesToExcel.Run(CurrentUser.Email; team_names.Selected.team_name; Concatenate("Rapport_for_";Text(team_names.Selected.team_name))).return;

Navigate(successReport;ScreenTransition.Fade);

Notify("Error"; NotificationType.Error));;

What is the error facing?

And how long the flow runs?
