Thanks for the report. I think your compiler version is too old. The function or_insert_with_key has been stable since Rust 1.50.0 (see here and texlab requires 1.51.0+). Please try updating your compiler. Also, be sure to use the --locked flag in conjunction with cargo install if not done already.
