I have it running and saving finally. I installed through lutris. From another thread I was going support:

I installed to /home/user_name/Games/the-sims-4/drive_c/users/windows_user/Games/The Sims 4/Game/Bin/TS4_x64.exe and it is saving, it is launching. I will let you know how it is doing once my wife has played a bit. Thank you very much for helping me with this.

I am going to dig into what you wrote because it looks like there is a lot of amazingly useful things in it. I really appreciate your help with this. And my wife is currently making a sim.
