copy or duplicate sandbox

Yes, double quotes are once more not needed. Thanks.

Mitch -

The problem is that Windows launches rundll32 to display the Open With dialog box. Rundll32 runs in the folder you're exploring, and that happens to be a forced folder. So rundll32 runs sandboxed. But you have a rule to block unknown programs from executing, so rundll32 can't run at all.

Looks like everything is behaving according to your configuration.

I was not aware of that, thanks.
