Unable to download game

I have had a lot of issues with the Sims 4 on the EA app on my Mac. The first issue being that the error code 10005 comes up and says that the EA app cannot connect to the servers. When I restart my mac, I am able to open the app. But if I close the app, I cannot open it again until I restart my mac. When I first got back onto the app, I was unable to download the latest update on the Sims 4 game and couldn’t access it. I tried everything and then thought that deleting my game and reinstalling it would work. However, I am now unable to download the game again as it stops every time I try. I have tried using an Ethernet cable, using my phone data (which seems to work but I don’t have enough data for) as well as my WiFi, but nothing is working. Does anybody know what else I can try as I’ve run out of options!
