Hello Friends

I am currently developing a framework that offers a SwiftUI menu among other things. In this menu I use a normal FileImporter.

import SwiftUI
import UIKit
import UniformTypeIdentifiers

struct SimulatorConnectionView: View {
    
    @State private var isImporting: Bool = false
    @State private var fileSelected: Bool = false
    @State private var filename: String = "Select File"
    @State private var url: URL = URL(string: "/")!

    var body: some View {
        VStack{
          

            // some code 


            HStack {
                StandardButton(title: filename, width: 250, locked: false, action: {
                        isImporting = true
                })       
            }
         
          
            // some code 


        }.fileImporter(
            isPresented: $isImporting,
            allowedContentTypes: [UTType.text],
            allowsMultipleSelection: false
        ) { result in
            do {
                guard let selectedFile: URL = try result.get().first else { return }
                url = selectedFile
                fileSelected = true
                filename = selectedFile.lastPathComponent
            } catch {
                // Handle failure.
                print(error.localizedDescription)
            }
        }
    }
}

I’m using XCode 14.3.1 and I’m building for an iPad Air (4. Gen) with iOS 16.2

When I now run the application that uses the framework and open the FileImporter, the standart window opens. But after a certain time, it starts to flicker and eventually crashes. The following Error Message occurs:

2023-08-29 09:36:37.652586+0200 “MyApplication” [2161:397002] [lifecycle] [u 8130AA3A-2C68-4F54-91D0-9CA032B2644F:m (null)] [com.apple.DocumentManagerUICore.Service(1.0)] Connection to plugin interrupted while in use.

Unfortunately, I’ve no idea what this messages want to tell me and google couldn’t help me ether so far. Has maybe someone an idea what the problem could be or can give me at least a hint in which direction I have to search?

Kind regards
