AppVerifier stops in Windows Terminal 6c7dfd2ce45841d32f3990147506de2f7903485d amd64fre.txt

=======================================
VERIFIER STOP 0000000000000305: pid 0x64: Incorrect object type for handle. 

	FFFFFFFFFFFFFFFF : Handle value.                                     ==> INVALID_HANDLE_VALUE

	00007FFE88E46900 : Expected object type name. Use du to display it   ==> "Event"
	0000000000000000 : Not used.

(Between stack frames 4 and 5, a call to ...::Render::RenderThread::NotifyPaint()
 through the ...::Render::IRenderThread::NotifyPaint() interface has been inlined.)

This happens during Terminal app startup.

This is because in TermControl::_InitializeTerminal(), the TermControl
creates a RenderThread and passes it to the Renderer. However, the
TermControl failed to call RenderThread::Initialize() before passing it
to the Renderer, so when TermControl subsequently calls into Renderer,
it tries to use an uninitialized RenderThread.

The verifier break occurs because the RenderThread has
a handle to a Win32 event (_pEvent), the RenderThread is
uninitialized so the handle is null, and the wrong null value
was used for the HANDLE variable (not 0, but INVALID_HANDLE_VALUE).

Same as the previous stop, also in Terminal app startup.
The same problem just repeats itself again because
TermControl makes multiple calls into the Renderer
after giving that Renderer an uninitialized RenderThread.
