I can't do anything with my Sim.

Every time I try to interact with other Sims, I only see the option to give a gift, but it won't let me have any other interactions. Besides that, I can't level up any skills because every time I start an action, it's automatically canceled.

It won't let me use items unless I'm converting them into relics.

At first, I thought it was just one of the thousands of bugs everyone was experiencing, so I waited for the update, but nothing changed. Then I tried repairing the game, but that didn't work either, and I don't have any mods installed, so I don't think that's the reason. 

I don't know what to do anymore.
