I couldn't set autocomplete mode in VSCode

Describe the bug
I couldn't set autocomplete mode in VSCode

Version
CodeQL 2.17.5 and latest VSCode extension for CodeQL.

To reproduce
codeql-custom-queries-cpp/codeql-pack.yml

---
library: true
warnOnImplicitThis: false
name: getting-started/codeql-extra-queries-cpp
dependencies:
  codeql/cpp-all: ^1.1.1

.vscode/settings.json

{
    "codeQL.createQuery.qlPackLocation": "/test/src",
  "files.exclude": {
    ".cache": true,
    "out": true
  }
}

test.ql

import cpp

from File f
select f, "Hello, world!"

I couldn't autocomplete when I inserted "import"
Also, "f" too.
What am I missing?
I'm testing macOS and remotely to Linux server.
And I connected to Linux server with SSH server.

Any updates on this?
Facing same problem on M1. Also, CodeQL extension keeps activating but the extension log looks clean.
