The gfx-hal gl backend doesn't work on windows and shouldn't be compiled on the platform. How are you depending on gfx-hal?

[IronThread]

I have gfx-backend-gl = "0" on my dependencies table.

You need to put the backend behind a platform specific dependency, see https://github.com/gfx-rs/wgpu/blob/v0.9/wgpu-core/Cargo.toml#L49
