Trouble running Rust project

I have been scouring the docs, code, and build.rs files for a while trying to figure out of I'm doing something incorrectly. After cargo install pyoxidizer I created a new rust project via pyoxidizer init-rust-project newproject, I added jemalloc to the default features. However, when I try cargo run --release everything builds but it just sits there not proceeding past the call to MainPythonInterpreter::new(config). Logging before this call is fine, but it never seems to get past it.

I tried using a custom PythonConfig as described in the book but no matter what I've done I cannot get past the ModuleNotFoundError: No module named 'encodings' error.

I have attempted this on Debian 10 and Arch with the same results. Hopefully I'm just missing something simple.

Reproduce the issue with cargo install pyoxidizer, pyoxidizer init-rust-project newproject, and cargo run --release on a supported environment. Start by reading the generated build.rs, the MainPythonInterpreter::new(config) call, and the linked PythonConfig documentation. Done means the project starts past initialization without hanging or reporting ModuleNotFoundError: No module named 'encodings'.
