This is not my area, but what about Rust or Odin?

Rust is slow to compile, and not that productive when writing gameplay code (see https://loglog.games/blog/leaving-rust-gamedev/)

Odin... technically not a scripting language, and haven't used it that much. But if compile times are good enough and hot reloading works, might worth a try. Though I think manual memory management can be antithetical when churning out gameplay code quickly (or when you're working with game designers with minimal background in programming)
