Testing on a vanilla (no mods/cc) folder is the best way to investigate causes of issues.

Go to Origin launcher and right click on the game and choose the repair option.
Test with a new save game without putting anything back to see if the issues are still there.
Next put a copy of the saves folder (from The Sims4_Backup folder) to see if you can now add the desired relationship.
