[Rust]External terminal does not open in VS code

[Kangaxx-0]

My dev box is configured with WSL2 + Windows Terminal + VSCode 1.66.2, when I set CodeLLDB launch terminal to external, hitting debug did not open terminal at all, and I saw it took a lot of time(4 mins) to hit my first breakpoint(first line in my Rust hello world program). Whereas, integrated terminal works totally fine.

Did I miss anything to set up the external terminal successfully?
