DirectoryNotFoundException thrown during glob evaluation

**Operating System**: `Windows`
**DocFX Version Used**: 2.45.1.0
**Template used**: `default`

I'm running docfx on a folder which contains some deeply nested paths (Yarn / NPM). I get a `DirectoryNotFoundException` related to one of these paths as soon as I run docfx.

I have tried to exclude this path using the `exclude` below, since I am not interested in running docfx on these folders - but this technically requires the glob to be evaluated against the package cache anyway in order to exclude it.

```
"exclude": [ "**/packages-cache/**", "**/node_modules/**" ]
```

If I use the config below (no globbing), it works as expected:

```
"src": [{ "src": "../../", "files": [ "*/*.csproj" ] }]
```

Full exception is:

```
System.IO.DirectoryNotFoundException: Could not find a part of the path 'D:\Working\Blah\Blah\trunk\MyWebApp\build\packages-cache\v4\npm-babel-plugin-transform-cjs-system-wrapper-0.3.0-f5759f29becd356faab7af52c99cde8e7bad0b21\node_modules\babel-plugin-transform-cjs-system-wrapper\test\fixtures\not-return-module.export-if-module-redeclared-in-scope'.
