I have encountered the same issue after trying to update “Vulnerable packages” following by VS hint.
I think it changed something in the UE source files, so what helped me:
MY SOLUTION:
- Go to Epic Games Launcher → Unreal Engine.
- Find your engine version.
- On the right from yellow “Launch” button there is dropdown menu
- Choose “Verify” option
It will check all engine files for identity with the release ones and reinstall required files.
Note: I have encountered “Queued” status, and it didn’t change. Windows restart fixed it.
I hope it will help you.
Best regards.
