Hello, I'm doing rustlings exercise on Mac (M1 Pro, Sonoma 14.5). For Clippy exercises, rustlings couldn't write to Cargo.toml file inside 22_clippy folder. I verified that clippy is installed since I could run cargo clippy

Checking rustlings v5.6.1 (path/to/rustlings)
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.38s

Error message

When running RUST_BACKTRACE=full rustlings run clippy1, the output to the terminal is:

The code panicked at this part:

What I tried

I manually created Cargo.toml file inside 22_clippy folder
I granted write permissions to both exercises and src folder, but the issue remains the same
I checked that the path to Cargo.toml file exists and the terminal is running at the project root rustlings

const CLIPPY_CARGO_TOML_PATH: &str = "./exercises/22_clippy/Cargo.toml";

I ran the project inside Dev Container and it was even worse: not recognize rustlings command.
