Loading is stuck, flush will never finish

The project cannot be successfully packaged after updating the project from 5.4 to 5.5.3.

LogWindows: Error: Fatal error: [File:C:\UnrealEngine-5.5.3-release\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading2.cpp] [Line: 9991]
LogWindows: Error: Loading is stuck, flush will never finish

It was solved after using “ResavePackages -projectonly -autocheckout -all”, but this error occurred again when a new plugin was enabled.
