Setting up Query in init causes app to freeze

I'm trying to filter results to get all characters that are associated with a story. When navigating to the view it filters as it should, but as soon as you select the Add Character option, the app just freezes.

I've found that if I comment out the Query line in the init, and filter out as part of the foreach I don't get the freeze.

Can anyone advise how I should be doing these predicates as it seems init isn't the best place to do it

The views code is

import SwiftUI
import SwiftData

struct CharacterListView: View {
    let story : Story
    @Query(sort: \Character.name, order: .forward) private var characters: [Character]
    
    var body: some View {
        List {
            ForEach(characters) { char in
                CharacterListCellView(char: char)
            }
        }
        .toolbar {
            ToolbarItem {
                NavigationLink(destination: CharacterAddView(story: story)) {
                    Label("Add Character", systemImage: "plus")
                }
            }
        }
        .navigationBarTitle("Characters", displayMode: .inline)
    }
    
    init(story: Story) {
        self.story = story
        
        let id = story.persistentModelID
        let predicate = #Predicate<Character> { char in
            char.story?.persistentModelID == id
        }
        
        _characters = Query(filter: predicate, sort: [SortDescriptor(\.name)] )
    }
}

I've narrowed it down to a line in the AddCharacterView file

struct CharacterAddView: View {
    @Environment(\.modelContext) private var modelContext
    @Environment(\.dismiss) var dismiss
    
    let story : Story
    
    // Character details
    @State private var characterName: String = ""
    
    // Images
    @State private var showImageMenu = false;
    @State private var isShowPhotoLibrary = false
    @State private var isShowCamera = false
    //@State private var image = UIImage() <-- This line
    
    @State private var imageChanged = false
    
    @State private var isSaving : Bool = false
    
    var body: some View {

    }
}

If I do either of the below it works

If I comment out the UIImage variable then I don't get the freeze, but I can't update the image variable

If I comment out the query in init, then it works but doesn't filter and I have to do it as part of the foreach
