Solution

1, Disable Niagara: Settings -> Plugins -> FX , disable all plugins related Niagara.

2, Modify engine source:
Engine\Source\Runtime\CoreUObject\Private\Misc\PackageName.cpp

Change this Log Level to Warning in function FPackageName::DoesPackageExist(), origin is Error

if ( !FPackageName::IsValidLongPackageName( PackageName, true, &Reason ) )
{
    UE_LOG(LogPackageName, Warning, TEXT( "DoesPackageExist: DoesPackageExist FAILED: '%s' is not a standard unreal filename or a long path name. Reason: %s"), *LongPackageName, *Reason.ToString() );
    return false;
}

This modification’s purpose is to ignore following error log:

UATHelper: Packaging (Windows (64-bit)):   LogInit: Display: LogPackageName: Error: DoesPackageExist: DoesPackageExist FAILED: '/Niagara/DefaultAssets/DefaultSpriteMaterial' is not a standard unreal filename or a long path name. Reason: Path does not start with a valid root. Path must begin with: '/Engine/', '/Game/', '/Paper2D/', '/AnimationSharing/', '/Cry
