Again Crash. Dynamic created RenderTarget

I wanted to create an Actor for every Player on the Map, that includes a greenscreen for a picked up item.

The Actor includes RenderTargetComponent2D and also A Dynamic Material Instance Reference and also a RenderTarget2D Reference.
The RT2D Reference is Created via Construct Object Node. The Dynamic Material Instance has a Parameter that takes the RT2D.

Now whenever I want to open the Blueprint, the Editor crashes.

I encircled the Crash:

The Blueprint crashes If i set the RenderTarget2D Reference to a newly created one.

It does NOT crash when constructing the Object. Only If I set a reference to it.

Solved.

Instead of constructing a new RenderTarget2D Object.
I used Create Canvas RenderTarget2D. Which returns a RenderTarget with a specified size.
