On my work computer (Windows 11), the script displays "Is index 0 enumerable? No" and fails to enumerate the array

On my home computer (Windows 10), the script displays "Is index 0 enumerable? Yes" and enumerates the array.

I don't know if this difference of behavior is caused by the different version of Windows, or some security settings on my work computer, or something else entirely. I need more data-points.

Thanks!

Array length: 1
Key at index 0: undefined
Is index 0 enumerable? No
for-in loop:

So you have the same behavior as my work laptop, interesting. On Twitter one person tested with W11 and didn't see that behavior.
I'm wondering, what security solution are you using? Would it be SentinelOne by any chance?

Nope. Just Windows Defender.

Ok. Well, this is getting more and mysterious. Thanks for the help.
