let line_col = line_index.index.line_col(offset);

It seems that just ignoring this error can make RA work again

    let line_col = match line_index.index.try_line_col(offset) {
        Some(line_col) => line_col,
        None => return lsp_types::Position::new(0, 0),
    };

Minimal repo:

Just invoke callHierarchy/outgoingCalls on take method

fn main() {
    let _a = Some(5).take();
    //               ^^^^   Invoke outgoing call hierarchy here!
