EON Assert "leaking an error!"

When working on ConceptStation and moving into the Visualize portion of LumenRT I'm getting an EON Assert that pops up. 

When I press okay this pop up happens

If I cancel/ok a couple more times it eventually opens LumenRT but only has green grass and a square building. Is there a reason why this is happening? It wasn't an issue in previous versions of ConceptStation/LumenRT. 

I've removed the program from my computer and reinstalled it. Not sure how else to fix this.
