WebEngine crash when QWebEngineProfile and QQuickWebEngineProfile are set to same persistent storage path:

QQuickWebEngineProfile *pDefaultProfile = QQuickWebEngineProfile::defaultProfile();

pDefaultProfile->setPersistentStoragePath("testPath");

QWebEngineProfile *pCustomProfile = new QWebEngineProfile("newProfile");

pCustomProfile ->setPersistentStoragePath("testPath");

Check failed: !HistoryPathsTracker::GetInstance()->HasPath(history_dir_). There already is a HistoryBackend running using the file at: path. Tests have to make sure that HistoryBackend destruction is complete using SetOnBackendDestroyTask() or other flush mechanisms before creating a new HistoryBackend that uses the same directory.
