    Description

      I found this crash among our users crashlogs, after analyzing minidump I see the next:

      Call stack:

       	Qt6WebEngineCore.dll!base::Value::FindPath(base::BasicStringPiece<std::string> path) Line 541	C++
 	[Inline Frame] Qt6WebEngineCore.dll!base::DictionaryValue::Get(base::BasicStringPiece<std::string>) Line 1177	C++

 	Qt6WebEngineCore.dll!QtWebEngineCore::WebEngineContext::createDefaultProfileAdapter() Line 532	C++
>	Qt6WebEngineQuick.dll!QQuickWebEngineProfile::defaultProfile() Line 733	C++

      *this* was nullptr.

      Most probably this happens when pdfManifestDict pointer is null in ExtensionSystemQt::Init(). But I have no idea when and why it might be NULL for certain users.
