Azure Virtual Desktop | Custom image templates | Failing on Language scripts reboots

Hi Everyone + @murajput
I cannot finish an image build from _Azure Virtual Desktop | Custom image templates _
I have noticed that if I remove the Language scripts the build finishes fine.
In the json file I can see that a reboot is added automatically after the language scripts.
Is there a way out of this?

See attached part of that customization.log
