What is the ConX setup experience?

I recently tried to update my windows 11 24H2 and got an error message that says

 

"Installation Failure: Windows failed to install the following update with error 0xC1900106: Windows 11 Insider Preview 10.0.26120.X (ge_release_upr)."

 

While looking up the logs, I found entries like:

 

Determining whether we should run ConX or legacy setup
Date-time, Info                  UI     Will launch ConX setup experience
, Info                  UI     Initializing Media class driver for audio support
, Info                  UI     Initializing media class driver status: 126
, Info                  UI     Launching ConX setup experience
, Info                  UI     Inspecting ConX Setup Cmdline
, Info                  UI     Launching C:\$WINDOWS.~BT\Sources\SetupPrep.exe 
 

I am wondering what is this new setup experience?

Is there any configuration which could be changed for using legacy setup?

The setup failed. Where could I find detailed diagnostic log? Event viewer did not show any relevant log entry for this failure.

    ConX aims to provide a more responsive and user-friendly upgrade process. It enhances features like the installation flow, the way updates are delivered, and the overall efficiency of the setup procedure. It’s particularly beneficial for users on fast connections or newer hardware.
