Xcode run simulator does not work

Hi all! I created an Xcode 11 beta 7 project and wanted to run an app simulator to see how it works. Whenever I start it, it just forwards me to a Home page, without so much as a warning or error message. So I ran a debugger and got this message:

“Can’t end BackgroundTask: no background task exists with identifier 1 (0x1), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.”

Anyone knows that is this about?

hey there!
