Sims 3 expansion packs fail to appear on launcher

Someone help before I blow my top. I haven't played sims in years ever since the failure I thought sims 4 was so I stayed loyal to sims 3. I just jumped on a 3 day binge after years of a hiatus. Last I played was when EA had just eliminated Origin. Clearly, this has created nothing but a mess and I have nothing but distain for the EA app. When I log into my EA app, everything is in working order. My sims 3 base game appears and my TWENTY expansion packs all appear under the "manage add-ons" drop down... AS THEY SHOULD! HOWEVER! For whatever reason when I go to play and it jumps to the game launcher, only FIVE of my TWENTY expansion appears for me to choose to play from. For the last few days I have settled for it, but I am missing so much from not being able to access the expansion packs I want! I have spent two days, formed several fists, officially sent a report to EA and continue to go down the rabbit hole of forums and reddit posts to fix the problem and NOTHING is working. What I have heard working for other people is for some reason not working for me. After two days I finally found where to "re" download the origin app and it won't let me open after download claiming it "cannot connect to internet." Now with the origin downloaded, my EA app greyed out the play button for Sims, meaning I cannot access my game at all with the Origin app on my PC. So I either trouble shoot the origin app in hopes that I gain access to all of my games by forcing the use of the OG app... or I uninstall it and figure out how to work with EA app despite my hatred for the forced change in launchers.

I am beyond frustrated..... please help and I DO NOT TELL ME TO UnIStALL aNd ReINsTaLL the game... I HAVE... MANY TIMES.

Thank you.
