RunOnceEX is no longer executed

[DMD]

Good morning.
I am struggling with a strange RunOnceEx situation.
I have been using this procedure for years from W7 up to W11 22H2 and it works regularly on both HOST PC and virtual machine, but these days an unexplainable thing happens to me.
When I run this procedure on a newly built pc with Ryzen 9 7950X and still running W11 22H2, the RunOceEx does not run, when I try the same ISO with RunOnceEx on another PC or virtual machine it runs.
I have been going crazy for a few days and can't figure out why and don't know what solution to look for.
Any ideas?
This is the "setupcomplete.cmd" script that I have always uitilized.
