Sims 4 Posture Issue?

I have had this issue for about a week now. I tried Better Exceptions report and it tells me that its a ""interactions/constraints.py" Issue. I've went to their Discord server and they told me it's best if I were to write it in EA Forums. 
Someone told me it's also a posture issue as well. For example, A Sim holding an umbrella while they were swimming. 
I've removed all my Mods and Scripts, and fully deleted them as well and the issue still occurs. Is there anyway someone can fix it? Like a proper step-by-step method for me to follow? Nobody has helped me or given me proper instructions either. I'm starting to think this is an EA Issue.

Thanks :)
