Build Rect Painter Sample for linux-arm64

[shirasp-bh]

I am able to build & run all the Avalonia.Samples projects @ https://github.com/AvaloniaUI/Avalonia.Samples using VS2022 on Windows. I wanted to run these samples on my Arm64 target running embedded Linux. When i do "dotnet publish -c Release -r linux-arm64 --self-contained" in VS2022 terminal, it succeeds, but when i run the published binary (for eg: the RectPainter) after copying the whole publish directory to my target, i see the below output.

Unhandled exception. System.InvalidOperationException: Default font family name can't be null or empty.

I am new to Avalonia.. Any idea, what am i missing here? Is my procedure to cross compile for linux-arm64 correct?
