Windows 10 20H2 19042.906 x64 here, and still working. Increasing those indexes didn't work here, it might have been some adjustment that changed the index position/extra byte in yours. 🤔

Interesting, I'm on the same version as you. Well, if yours ever does mysteriously stop working, verify the byte offsets didn't change.
