Running "Check" produces "Failed to launch checking..." error. I looked in tests.rs and noticed it's empty. Adding tests from https://github.com/rust-lang/rustlings/blob/main/exercises/13_error_handling/errors6.rs to tests.rs then running "Check" again results in the tests.rs filed getting cleared before running again to produce the same error.
