SKPath.ParseSvgPathData is null on wearable

[luvjungle]

I am trying to run those samples on Galaxy Watch 3 with Tizen 5.5
Wearable/Xamarin.Forms/SkiaSharp2DSample
Wearable/Xamarin.Forms/PlayingWithHWInputs
but either of them are crashing with null reference to result of SKPath.ParseSvgPathData
I tried using different SkiaSharp versions, but that didn't help.

Could you try it with Tizen 5.5 Wearable emulator ?
and, let us know the firmware version of your Galaxy Watch 3 device.
thanks in advance.

I can't run emulator. It says "your system cannot support HW acceleration". I have windows 11, AMD Ryzen CPU with virtualization turned on in BIOS, Hyper-V disabled. CPU VT turned off in emulator settings.
Watch firmware is SM-R840NZKASER

F.Y.I: hw acceleration with Windows

And, could you share the log when SKPath.ParseSvcPathData is null?

As I wrote, I have AMD Ryzen CPU. HAXM is for Intel.

Here is the log

Could you check SkiaSharp version? Verified version for this app is 1.68.2-preview.50. If you've updated it via Nuget manager, I think.. it does not work correctly..
