Hey @MysticRyuujin, thanks for the bug report.

Unfortunately, native Windows support is a long way off, and is being tracked in issue #1237. I'll update the docs today to make it clearer that Windows is only supported via WSL for now (and I'm going to double check that WSL does work).

Hey @2naive that looks like an issue with an old Rust compiler, try running rustup update stable and recompiling. When you run rustc --version it should show v1.45.0 or better (probably v1.45.2)
