Infinite Loading Screen Issue with Growing Together Expansion

Hi KhloudM​ 

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

- Delete the ones you have
- Trigger the error again
- Check if new ones are created
- If that is the case, please copy/paste the content here. You can open the file with any text editor.

Deleting the file won't fix your issue. Posting the info is meant for troubleshooting.

I noticed milestones mentioned in the LE. Did any Sims gain a milestone associated with a CC build mode item and then removed the CC from your game?

For the milestone_tracker issue please follow instructions on the first post here: [GRO] [SNK] LE: developmental_milestone_tracker.py/Endless loading | EA Forums - 11692228 

The other possibly an issue with an household item. Try if it loads if you fix the milestone
