MAUI Popup at first start

Since OnAppearing is kind of an Event Handler of sorts, you can probably get away with making it an async void method. Generally, you wouldn't want to do that unless it is an event handler method. In this context you probably could to navigate.

protected override void void OnAppearing()
{
    base.OnAppearing();

    bool GCUAccepted = Preferences.Get(Constants.GCU_ACCEPTED_KEY, false);
    if (!GCUAccepted)
    {
        GCUPopupPage page = new();
        await popupNavigation.PushAsync(page);
    }

    // ....
}

protected override void void OnAppearing()
{
    base.OnAppearing();

    bool GCUAccepted = Preferences.Get(Constants.GCU_ACCEPTED_KEY, false);
    if (!GCUAccepted)
    {
        GCUPopupPage page = new();
        await popupNavigation.PushAsync(page);
    }

    // ....
}

Brotli compression with all cores

This is a harder problem than it probably first appears... In order to have multithread compression, you'd have to break the file into chunks (Look into the Partitioner class for that), and then use a Parallel.ForEach to compress each chunk. And while that would work... you'd have to decompress each chunk and re-combine the exact same way. The order of chunk has to be persisted as metadata in order to decompress later.

✅ How to use IRelayCommand in CommunityToolkit.Mvvm with parameters?

There is also a dialog window in VS that is "XAML Binding Failures" I think. That's a good one to keep your eye on while running the app

✅ How to use IRelayCommand in CommunityToolkit.Mvvm with parameters?

Specifically the Mode=TwoWay part may help if you plan to set that value from code and from the UI toggle

A problem while making a request for API in maui .net

I'd recommend leowest's suggestions. The cleartext one anyway, as that can cause requests to fail. My assumption of the issue here is that your android emulator is probably not serving HTTP content locally on port 5117 like your PC is. If you inspect the request object, I'd be interested to see why it failed. If you get a HTTP status code, then you know at least it is hitting the HTTP server

✅ How to use IRelayCommand in CommunityToolkit.Mvvm with parameters?

Although, the CanExecute becoming false will no longer allow you to execute that command to turn it back to true, so instead you could try

[ObservableProperty]
private bool _isCodeOutliningVisible;

[RelayCommand]
private void TestRC()
{
    // Implementation using IsCodeOutliningVisible

    if (IsCodeOutliningVisible)
    {
        // ...
    }
}

[ObservableProperty]
private bool _isCodeOutliningVisible;

[RelayCommand]
private void TestRC()
{
    // Implementation using IsCodeOutliningVisible

    if (IsCodeOutliningVisible)
    {
        // ...
    }
}

<ToggleButton x:Name = "CodeOutliningVisibleBT"
              Content="Dave"
              ToolTip="Toggle Code Outlining"
              IsChecked="{Binding IsCodeOutliningVisible, Mode=TwoWay}"
              Command="{Binding TestRCCommand}">
</ToggleButton>

<ToggleButton x:Name = "CodeOutliningVisibleBT"
              Content="Dave"
              ToolTip="Toggle Code Outlining"
              IsChecked="{Binding IsCodeOutliningVisible, Mode=TwoWay}"
              Command="{Binding TestRCCommand}">
</ToggleButton>

✅ How to use IRelayCommand in CommunityToolkit.Mvvm with parameters?

Have you tried something like

[ObservableProperty]
[NotifyCanExecuteChangedFor(nameof(TestRCCommand))]
private bool _isCodeOutliningVisible;

[RelayCommand(CanExecute = nameof(IsCodeOutliningVisible))]
private void TestRC(bool isCodeOutliningVisible)
{
    // Note: You likely don't need a param, you have the value available as a class field

    // Implementation...
}

[ObservableProperty]
[NotifyCanExecuteChangedFor(nameof(TestRCCommand))]
private bool _isCodeOutliningVisible;

[RelayCommand(CanExecute = nameof(IsCodeOutliningVisible))]
private void TestRC(bool isCodeOutliningVisible)
{
    // Note: You likely don't need a param, you have the value available as a class field

    // Implementation...
}

<ToggleButton x:Name = "CodeOutliningVisibleBT"
              Content="Dave"
              ToolTip="Toggle Code Outlining"
              IsChecked="{Binding IsCodeOutliningVisible, Mode=TwoWay}"
              Command="{Binding TestRCCommand}"
              CommandParameter="{Binding IsCodeOutliningVisible}">
</ToggleButton>

<ToggleButton x:Name = "CodeOutliningVisibleBT"
              Content="Dave"
              ToolTip="Toggle Code Outlining"
              IsChecked="{Binding IsCodeOutliningVisible, Mode=TwoWay}"
              Command="{Binding TestRCCommand}"
              CommandParameter="{Binding IsCodeOutliningVisible}">
</ToggleButton>
