I have been having issues while exploring. I was flying both of the times when the game closed suddenly and when I tried to open my save it shut down immediately every time.
I had to use a back-up as I couldn't seem to repair the saves.
Here is a log;

Thanks for all the efforts and I hope it gets fixed soon.
