VSCode rust plugin error : [init] function already declared

I wonder if anyone else have the same issue.
I am following the rust counter example
and I am getting an error in vscode from rust analyzer

However running cargo check doesn’t show any issues.
The issue also happens with the main rust plugin

"dfx": "0.8.4"
rust-analyzer: v0.2.890 updating to v0.3.896 also doesn’t solve the issue.

The issue is not a blocker but it’s just annoying.
