THIS IS NOT A QUESTION, IT’S A SOLUTION.
I came up with a workaround I could reproduce in other projects where I had reproduced the issue in. For me this was an issue on my pc and not mobile, because I’m making a pc/console game.
Anyway I didn’t find any workaround online but I had one level where my Scene Capture 2D/Scene Render 2D, didn’t cause the editor to crash so I figures some setting must be differen.
Then I went into the crash logs from before and saw a refernce to the light rendering failing.
So I compared two levels where one had bloom and other didn’t in the directional light settings, in the one with bloom I could plase a 2d capture/render blueprint and display, wihtout any problems. But the one without bloom crashed instantly when placed in world.
