Woohoo interaction greyed out for romantic partners

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.93.146.1020
What expansions, game packs, and stuff packs do you have installed? I have every pack
Steps: How can we find the bug ourselves? >Have a teenaged sim > Try and flirt with ANY other teenaged sim > fail 100% of the time > sim says "im just not interested in you" and FOREVER GREYS OUT ALL ROMANCE OPTIONS. FOREVER.
What happens when the bug occurs? - sim attempting the flirting does NOT have any anti-social traits. They have party animal and the outgoing one and the life of the party aspiration! They are literally designed TO MAKE FRIENDS. I have tried spamming social bunny and getting their relationship bar to 100 percent and THEN trying, still fails. I have loaded and reloaded my save at least 15 times trying to get a prom date. I have tried multiple sims. I have even cheated their relationship status to full and i am STILL at a 100% rejection rate. The target sim will even ASK ME to prom, then immediately turn down all advances. Them turning me down, again, FOREVER GREYS OUT THE OPTIONS FOR ROMANCE.
What do you expect to see? Failure to flirt, followed by PERMANENT rejection. I have literally made this dude 4 custom girlfriends, every single one of them has turned him down at full love bar.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

List of attempted fixes:

-Cheating relationship to full

-making the target sim playable and trying to flirt with the female sim

- changing EVERY sexual preference to fit the target sim EXACTLY

- cheating their relationship to 'very flirty' just before the interaction

- cheating their relationship bar to full, just before the interaction

- getting both friendship and relationship to full by cheating

- getting the relationship bar to full through social media (i cant use direct interactions, i will get rejected)

- getting both the friendship and relationship bar to full organically 

- cas-editing the target sims traits to flirty and romantic, all the 'flirty' traits

not a single one of these worked. I tried ALL OF THEM on 4 different females.
