Rust ssh2 download using scp - windows

Question

I've spent the day trying to use ssh2 to download a file by using scp. To test this I've set up a OpenSSH server on my localhost on port 22 and created some dummy files for the program to copy from one location to another. I'm running this on Windows 10 and I've not changed anything in my ssh config file since installing the OpenSSH feature this morning.
It works when I'm doing the following in cmd:
scp username#localhost:c/users/username/logs/from.log c:/users/username/logs/to.log
But for some reason when I'm running my program it exits with the following error:
Error: Error { code: Session(-28), msg: "Failed to recv file" }
This is the code I'm trying run and at row 10 (on the call to sess.scp_recv) is where I'm getting the error:
pub fn test_download() -> Result<(), Box<dyn Error>> {
let conn = TcpStream::connect("localhost:22")?;
let mut sess = ssh2::Session::new()?;
sess.set_tcp_stream(conn);
sess.set_timeout(5_000);
sess.handshake()?;
sess.userauth_password("username", "password")?;
let (mut remote_file, _) = sess.scp_recv(Path::new(r"c:\users\username\logs\from.log"))?;
let mut content = String::new();
remote_file.read_to_string(&mut content)?;
remote_file.send_eof()?;
remote_file.wait_eof()?;
remote_file.close()?;
remote_file.wait_close()?;
std::fs::write(r"c:\users\username\logs\to.log", &content)?;
Ok(())
}
I've been googling like a maniac and I can't find an explanation for this, so here I am. Note that I'm new to both Rust and ssh.
Update
I ran sshd.exe -d and connected using my program and the logging looks fine right up until the very end:
debug1: userauth-request for user user service ssh-connection method password [preauth]
debug1: attempt 0 failures 0 [preauth]
debug1: user domain\\user matched group list administrators at line 87
Accepted password for user from 127.0.0.1 port 52813 ssh2
debug1: monitor_child_preauth: user has been authenticated by privileged process
debug1: monitor_read_log: child log fd closed
debug1: Not running as SYSTEM: skipping loading user profile
**CreateProcessAsUserW failed error:1314**
fork of unprivileged child failed
debug1: do_cleanup
So it looks like there's some sort of privilege situation going on with Windows here.
Solved
I finally solved this by instead of using the scp_recv function I ran pscp -pw password -scp remote local using the std::process::Command crate and supplying the paths and password
