Hello!

In version 4.6.1, the node ‘Create Canvas Render Target 2D’ does not work; the editor will immediately crash on use (easy to reproduce, 100% repro rate).

Quick debugging shows the texture has been created correctly, but it fails to create the accompanying canvas, getting a null pointer from somewhere else in the engine. The root cause is this function call in void UCanvasRenderTarget2D::UpdateResource():

// Create the FCanvas which does the actual rendering.
	FCanvas RenderCanvas(GameThread_GetRenderTargetResource(), nullptr, FApp::GetCurrentTime() - GStartTime, FApp::GetDeltaTime(), FApp::GetCurrentTime() - GStartTime, GetWorld()->FeatureLevel);

Fixed on git.
