I am not able to restore the system

I am following the instruction on "Restoring Developer Transition Kit" to restore it (because my Xcode installation is broken). When I select the "Restore" on Apple Configurator in the step 4, it fails with the following error.

The operation couldn’t be completed. (AMRestoreErrorDomain error 10 - Failed to handle message type StatusMsg) [AMRestoreErrorDomain – 0xA (10)]
Here is the additional info.
  1. I am running Apple Configurator 2, Version 2.13.1 (5A35): The document says "2.13 beta 1", but it is not available at developer.apple.com

  2. The version I am trying to restore to is macOS Big Sur 11 beta 9

from https://developer.apple.com/download/universal/ (UniversalMac11.020A5384c_Restore.ipsw)
3. When I connect DTK (in DFU mode) to my MacBook, a popup appears with following message:
Apple Configurator 2 would like to update Device Support for currently connected devices.
When I select "Install", it fails with the following message.
Installation failed: Can't install the software because it is not currently available for the Software Update server.
4. I drag&dropped the .ipsw file, it starts restoring the device, but eventually fails with the following message:
The System cannot be restored on this device.
The operation couldn’t be completed. (AMRestoreErrorDomain error 10 - Failed to handle message type StatusMsg) [AMRestoreErrorDomain – 0xA (10)]
I am not able to restore the system
