are you using Windows 7?

[CodaWear]

I'm on windows 11 should I use 7?

[RSDuck]

no, I noticed that this function seems to be introduced in Windows 8.

If you aren't already, try building via ucrt instead of mingw64 and try updating packages (pacman -Syu).

EDIT: I should probably dynamically load this function as well for compability, though if you are running Windows 11, you should not be affected by this at all.
