SearchAllAssets in Android Crashes

It seems like an engine bug, but it was not resolved as of 5.4.1, so AndroidPlatformFile.cpp was modified as follows.

int64 GetEntryLength(const FString & Path)
{
	const FString& Dir = Path + TEXT("/");
	if (Entries.Contains(Path))
	{
		TSharedPtr<FFileHandleAndroid>& File = Entries[Path]->File;
		return File != nullptr ? File->Size() : 0;
	}
	else if (Entries.Contains(Dir))
	{
		TSharedPtr<FFileHandleAndroid>& File = Entries[Dir]->File;
		return File != nullptr ? File->Size() : 0;
	}
	else
	{
		return 0;
	}
	TSharedPtr<FFileHandleAndroid>& File = Entries[Path]->File;
	return File != nullptr ? File->Size() : 0;
}
