Random failures in InputLanguage_FromCulture_SupplementalInputLanguages_Expected

### Test

InputLanguage_FromCulture_SupplementalInputLanguages_Expected

### Issue description

Run test `InputLanguage_FromCulture_SupplementalInputLanguages_Expected` on my local machine, one or two or even three test scenarios ​​will fail because `language` returns `null` after executing the following code

```
InstallUserLanguage(languageTag);
CultureInfo culture = new(languageTag);
InputLanguage language = InputLanguage.FromCulture(culture);
```

But running them individually all pass and this problem does not occur in the pipeline run.
