Rust-analyzer raises an error when opening a project in WSL2

I have my rust development environment on top of WSL2 (kali-linux). After installing rust-analyzer from the marketplace in VSCode, I got this error on the hovering toast so that I cannot go forward.
rust-analyzer failed to load workspace: No such file or directory (os error 2)

Does the problem happen because rust toolchain is built on WSL2? If so, how do I solve it?
I've done a preliminary search about some relevant issues but I cannot find the answer yet.

Thanks in advance.
