WidgetKit Simulator on Big Sur - Unable to configure intent

We have create a new configurable widget with intent.
  • Big Sur beta 9

  • On DTK (Apple Silicon) and iMac

  • Xcode 12.2 Beta 2

Error Message when clicking "Configure" button in the Widget simulator: "Unable to Load:

We want to provide the widget for our existing app at the first day when Big Sur released. Any idea how can we test to configure the widget?
I asked the same question about Intel Macs: https://developer.apple.com/forums/thread/659420?answerId=637749022#637749022

Currently one person saying that it works, but I still have not had any luck.
