That's curious - I tried your exact code, except that I used v7.5.3 (both the SDK and the standalone PS 7 installation), and it doesn't work for me (Microsoft Windows 11 Pro (ARM 64-bit Processor; Version 24H2, OS Build: 26100.6584)).

@mklement0 indeed, 7.5.3 doesn't work for me either

Thanks for confirming; mysterious.

I've summarized the findings so far in a footnote to https://stackoverflow.com/a/79778070/45375 (which now links to this Gist).

If you come across further information, please leave a comment there.

@mklement0 If he doesn't know then we're surely out of luck 😅

Thanks; I appreciate the follow-up.
