研究方向
Investigate why `InputLanguage.FromCulture` returns `null` when tests are run together but not individually. Check if `InstallUserLanguage` has side effects that interfere with subsequent calls. Look for shared state or static variables in the test class that could cause ordering dependencies. Consider adding a retry mechanism or ensuring cleanup between tests.
