Solutions

1. Remove --browser-path so Selenium Manager can download the requested browser version
2. Or change the requested browser version to match the version installed at the given --browser-path
3. Or update/replace the browser installed at the given path to the requested version

When it happens

Trigger: Thrown at rust/src/lib.rs:553 when the library encounters an invalid state.

Common situations: Occurs when --browser-path points to a browser whose version conflicts with the explicitly requested version. Remove the explicit version, fix the browser path, or drop --browser-path so Selenium Manager downloads a matching browser.
