UE 4.5 Preview CanvasRenderTarget2d Causes Crash

I think the best way would be to explain how I got it working in UE4.4 and how it crashes in UE4.5.

In UE 4.4.3, I create a project based using the blueprint third person template (with the starter content).

First I create a folder named “CRT2D” (short for CanvasRenderTarget2D". Then I create the necessary assets in it:

-A blueprint named “MyCRT2D” with the parent class “CanvasRenderTarget2D”.

-A material named “MyMaterial” with a texture parameter named “DynamicTexture”.

-A font named “MyFont48” which is an Impact font with size 48.

I open the default MyCharacter blueprint and add a Static Mesh to it (Cube from the Shapes folder). Then I add an “Event Begin Play” node and wire it as shwon in the screenshot.

Then I open the MyCRT2D blueprint and arrange it to draw some text on the CanvasRenderTarget2D.

I took a screenshot to show that it works in the game.
