I noticed in the task "Travel to alien world":
1. When I created a new sim, game again got stuck on load screen.
2. When I created a new sim in the new game, game don't got stuck on load screen.
I also noticed that after the game stuck in the folder with the game was created a file:"lastException":

There seems to be an issue with the household inventory. Could you check if something is stuck there or weird ?
I found the reason for my problem.
In the world I had a family of aliens. Two adults and three babies. When I moved a babies to another family and removed it, the problem was resolved.
Also I will try: aged up babies to childs and see if this also helps.
