Unable to progress with Story

Hello, 

The other day I went in to play my game and continue with the mission I had left off on. At first everything appeared fine, but I was unable to proceed as the planet story quest was not appearing for me to grab to continue down to the planet. I returned to my ship and tried again multiple times with nothing changing. After many attempts I closed my game and reloaded and now am unable to even click on anything and get this error below. 

I'm at my wits end on trying to figure out what to do to be able to proceed further on this. Anyone able to assist? 

For reference the mission is Thanaton Strikes Back and I was having issues with the Quesh planetary mission.
