描述
We have an issue with CodeQL analysis where it would hang while extracting the files from the PR.
I've found which part was causing this and made a separate reproducible code snippet.
Here's a minimal reproducible example:
```
class Test {
static methodA>() {}
static methodB>() {}
}
```
Output logs
```
➜ temp-codeql-bug codeql version
CodeQL command-line toolchain release 2.19.2.
Copyright (C) 2019-2024 GitHub, Inc.
Unpacked in: /home/dubenko/codeql
Analysis results depend critically on separately distributed query and
extractor modules. To list modules that are visible to the toolchain,
use 'codeql resolve packs' and 'codeql resolve languages'.

Codeql only hangs if there are two methods, if you remove one of them it works.
