Cannot join azure - autoprovisioning not working

Hi,
first of all, my Parallels version is a Pro Edition.
I created a Windows 11 VM on my Mac Studio M2 Ultra (it is the third Win11 VM on my Mac, the other 2 had no need of joining a company domain on Azure and they are perfectly working). After the initial config, I resetted it to default state before installing using System->Recovery->Reset this PC and then restarted , as we always do for our company PCs.
At the initial screen I pressed SHIFT+F10 , opened a cmd prompt and typed in the usual commands as per our instructions;
PowerShell.exe -ExecutionPolicy Bypass
Install-Script -name Get-WindowsAutopilotInfo -Force
Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned
Get-WindowsAutopilotInfo -grouptag <<OURGROUPTAGNOTDISCLOSED>> -Online
It worked for a couple minutes and then it succeeded. The record has been correctly created in our Intune Company Portal, and I can see the serial number as being Parallels xx-xx-xx-xx-xx-xx-xx-xx
Then I moved to the next screen and pressed 5 times the Windows key (aka the command key), and clicked on Autoprovisioning (the second button).
It waited for a few minutes before finding the machine, then with next the system stayed there for 10 minutes before giving an error (tpm attestation expired)
So far, I tried and retried (I tried also applying all the updates before going for autoprovisioning), but with no success
Is this something that can be fixed? In case, is the Parallels Business version needed? Or is it not a factor?
Thanks for your help
