ApplicationLanguages::PrimaryLanguageOverride will throw an exception that can't be caught if it has never been set before

[hoshiizumiya]

Describe the bug

I used Windows SDK PrimaryLanguageOverride api, because it doesn't work in the wasdk.

Exception thrown at 0x00007FFB1B3FB5AC in OpenNet.exe: Microsoft C++ exception: long at memory location 0x000000C3423FD068.

PrimaryLanguageOverride is empty(NOT SET)

'OpenNet.exe' (Win32): Loaded 'C:\Windows\System32\Winlangdb.dll'. Symbol loading disabled by Include/Exclude setting.
Exception thrown at 0x00007FFB1B3FB5AC in OpenNet.exe: Microsoft C++ exception: long at memory location 0x000000C33473C088.

Exception thrown at 0x00007FFB1B3FB5AC in OpenNet.exe: Microsoft C++ exception: long at memory location 0x000000C33473C088.

Steps to reproduce the bug

		try
		{
			m_initialLanguageOverride = ApplicationLanguages::PrimaryLanguageOverride();

			if (m_initialLanguageOverride.empty())
			{
				OutputDebugStringW(L"PrimaryLanguageOverride is empty(NOT SET)\n");
			}
		}
		catch (const winrt::hresult_error& e)
		{
#ifdef _DEBUG
			std::wstring msg = L"WinRT Exception: ";
			msg += e.message().c_str();
			msg += L"\n";
			OutputDebugStringW(msg.c_str());
#endif
		}
#ifdef _DEBUG
		OutputDebugStringW((m_initialLanguageOverride + L"\n").c_str());
#endif

Expected behavior

I do not think it is normal.

This appears to have the same root cause as #6118. Therefore, I am closing this as a duplicate.

@lauren-ciha They are not the same API, which this is window SDK 26100 rather than window app sdk 1.8. Please reconsider it.
