Hi, Version 0.10 of wireguard-nt and version 0.14 of wintun are using a slightly different API and ABI than previous versions. As such, make sure you're using the wireguard.h/wintun.h header file that comes with the DLL that you download. And if you're using the Go packages, make sure you've paired the latest commit with the latest DLL.
Thanks, Jason
