Smithy client: couldn't create connection to server

I got this runtime error:

[Error - 5:59:52 PM] Smithy client: couldn't create connection to server.
Error: spawn Unknown system error -88
	at ChildProcess.spawn (node:internal/child_process:420:11)

Where Highlighting is working, but nothing else is working like jump-to-definition.

I've just installed the extension today, on my:

• Macbook Pro M1
• macOS Tahoe 26.1
• VSCode version: 1.107.1 (Universal)

and here is my folder structure, as I usually open the workspace root folder:
