Paquet Builder 2026.2 - 'Restart Computer' action fails

I use a 'Restart Computer' action after installing a pre-requisite for my setup package.
This works fine with the installer built with previous PB version, but fails with PB 2026.2.
I rebuild the same project and test back-to-back on the same computer. Old version restarts
the computer, new version does not. Need some help here, thanks!
