The following test executes correctly on a "normal" disk (C:\) on windows, but not on a network shared drive. @peterhuene determined that this is because UNC paths are not handled correctly in cap-std.

wasmtime main.wasm --dir .

fn main() -> std::io::Result<()> {
    let path = std::path::Path::new("dir.tmp");
    std::fs::create_dir(path)?;
    assert!(path.exists());
    Ok(())
}

I've hit this while debugging a YoWASP application on a VirtualBox (mounted!) network drive. Makes that a bit annoying, although this is an admittedly obscure corner case.

I've started working on this in https://github.com/bytecodealliance/cap-std/pull/156, but I have a ways to go before I really understand how UNC paths work.

https://docs.microsoft.com/en-us/dotnet/standard/io/file-path-formats and https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file have some documentation about the different kinds of paths on Windows.
