WindbgTime-travel C# .NET 8.0 app: why is RenderOptions.ProcessRenderMode = RenderMode.SoftwareOnly;

I configured VS2022 with .NET 8.0, changing the Exception settings to enable all exceptions to be trapped.  With the "RenderOptions.ProcessRenderMode = RenderMode.SoftwareO", VS stops just like WinDbg/Time-Travel.  The exception is 8001010d 

the line in VS that stopped on is
HwndTarget.cs:
  line 1464:  return AutomationInteropProvider.ReturnRawElementProvider(handle, wparam, lparam, el);

Diving into other's sw, but seems https://learn.microsoft.com/en-us/dotnet/desktop/winforms/controls/how-to-make-thread-safe-calls?view=netdesktop-8.0 is at the root of the problem.  Windbg's default exceptions handling vs Time-travel vs VS 2022, where the defaults across the set tends to mask the issue.  So, Time-Travel doesn't require the software rendering, it's just set to stop on the exception's caused by the app's async implementation.
