what to do
@arpandutta,
Looks like you have been kicked out from the Windows 11 insider program. What is the current Build you have installed ?
Run latest PC Health Check from the link below and see what requirements are missing on your machine..
You may still get updates for the public build of windows 11, but not the insider updates unless you meet the hardware requirements and can rejoin the insider channel.
