+=== qt.workarounds.remove_service_workers
+Delete the QtWebEngine Service Worker directory on every start.
+This workaround can help with certain crashes caused by an unknown QtWebEngine bug related to Service Workers. Those crashes happen seemingly immediately on Windows; after one hour of operation on other systems.
+Note however that enabling this option *can lead to data loss* on some pages (as Service Worker data isn't persisted) and will negatively impact start-up time.
