        NavigationView
        {
            VideoButton()
        }
    }
}

Video Button Struct

struct VideoButton: View
{
    
    @State var isPlayerActive:Bool = false
    
    var body: some View
    {
        VStack
        {
            Button(action: {isPlayerActive = true}, label: {

                    Image(systemName: "play.fill").foregroundColor(.white)
                }
            })
            
            NavigationLink(
                destination:
                    PlayerSection(),
                isActive: $isPlayerActive,
                label:
                {
                    EmptyView()

Player Section struct

struct PlayerSection: View

    var body: some View
    {
        ZStack
        {
            Color.black

        }.ignoresSafeArea()
    }
}

No es necesario poner el botón para cambiar de vista

import SwiftUI
import AVKit

struct VideoPlayers: View {
    
    @State var isPlayerActive: Bool = false
    
    var body: some View {
        
        NavigationView {
            VStack {
                
                NavigationLink {
                    ReproductorVideo()
                } label: {
                    ZStack {
                        Image("cuphead")
                            .resizable()
                        .aspectRatio(contentMode: .fit)
                        
                        Image(systemName: "play.circle")
                            .resizable()
                            .frame(width: 100, height: 100, alignment: .center)
                            .foregroundColor(Color.white)
                    }
                }

            }
        }
    }
}


struct ReproductorVideo: View {
    var body: some View {
        VideoPlayer(player: AVPlayer(url: URL(string: "https://cdn.cloudflare.steamstatic.com/steam/apps/256705156/movie480.mp4")! ))
            .aspectRatio(contentMode: .fit)
    }
}

struct VideoPlayers_Previews: PreviewProvider {
    static var previews: some View {
        VideoPlayers()
            .previewInterfaceOrientation(.portraitUpsideDown)
        ReproductorVideo()
    }
}

Estaba checando y hay otro inicializador para NavigationLink en el cual solamente necesita el destino o lo que renderizara al presionarlo y un label, siento que puede ayudar porque así evitas tener un botón el cual tiene la imagen, y aparte tener un NavigationLink con un EmptyView, y solamente se necesita crear el NavigationLink

NavigationLink(destination: View(), label: {})
