Sims 3 expansion won't download

I'm not sure what you mean by EA ID

The base game installed for me with no problems.   

I decided to do a clean install.

I used CCleaner for the registry after uninstalling the game and making sure there were no more EA or Sims 3 files on my system.  After doing a restart, I had the same problems with a fresh download. I can download the base game - but none of the add-ons. Even with trying one at a time. World Adventures will not download for me.

I already know to used Task Manager to set affinity to use only one Processor.  After unselecting All Processors, I chose CPU1  (any suggestions here would be appreciated in case I need to choose a different one)

And so I went through the whole process again of uninstalling and cleaning up all of the left over files on my system because I had read that having an Asus motherboard might require a total shutdown (rather than a restart).

This did not fix the situation either.

In the launcher, I can see all of my Expansions and Stuff packs. They're all unchecked - except World Adventures (because I am trying to download it first - separately from the rest) and it will not download.

Can you Please tell me what I am doing wrong?  I have a new PC with windows 11,  a 2 TB drive, new Intel Processor, Nvidia 3090 (of which the Device Config Log recognizes and matched)

I am at a loss. Can you Please help with this issue?
