Different Windows issue: "The specified procedure could not be found"

[DrJKL]

Hey all,

I've been getting the error above any time I try to use the hot reloading in the nannou example (and my own nannou app).
I was able to get the bevy example to run and pick up changes. I've tried to find a significant difference between the two, but nothing I've found has worked.
I've tried copying over the .cargo/ directory, changing the toolchain, renaming files, probably other steps I've forgotten.

This is on Windows 10 Pro 22H2 build 19045.2728. Let me know if any other system information would be helpful.

I was able to repro this with:

• git clone https://github.com/rksm/hot-lib-reloader-rs.git hlr-repro
• cd .\hlr-repro\examples\nannou-vector-field\
• cargo watch -w lib -x "build -p lib" (separate PowerShell terminal)
• $env:RUST_BACKTRACE="full"; cargo run --features reload --target-dir "target-bin"

Full error
