Every friendly social interactions result in a negative outcome

Hi,

I have a major issue playing the sims 4 : I started a new save and tried to make friends. Unfortunately, every friendly social interaction (as small as the "get to know" interaction) will results in the deterioration of the relationship between the two sims (mine and the NPC).

I am quite desperate, the game has become clearly unplayable for me.

I removed my Electronic Arts file and repaired the game. I then launched the game without putting back my old saves/tray/etc... but nothing changed.

Thank you for your help.
