PyOxidizer cannot find configuration file despite specifying path

I am using PyOxidizer for a project on Windows 11. PyOxidizer version is 0.24.0 and Rust version is 1.80.1.

When I run the command pyoxidizer build --release --verbose -- --config-file E:\cwxm\config\pyoxidizer.toml, I get the error message error: unable to find PyOxidizer config file at..

I have confirmed that the configuration file path is correct, the file exists, and I have sufficient permissions to access it. I have also tried reinstalling PyOxidizer and checking the environment variables, but the problem persists.

Does anyone know how to solve this issue?

Thanks in advance!
