Thank you, I will try it out

After waiting on live chat for 2 hours my best bet is to try to fix it on my own. Please wish me luck.

I have reinstalled the whole game and it works. But thank you very much for your suggestion.

The game is in Czech again so I really hope, the next update will run smoothly and the text/code bug is solved by now.

Good to hear.

Could you accept a solution if you're happy for now. You can always unsolve should it come back

I have the same problem. Did you already find the solutions? (I don´t want to reinstal the game ☹️ ) Instaled language czech.

Have you found any solution?? (I have the exact same problem.)

First of all, I updated Origin, then I wanted to update The Sims 4 but Origin wouldn't open so I reset it, then after the uninstalling and reinstalling Origin The Sims 4 won't open because of some language issues, so I repaired it. And it doesn't work. I don't want to lose any data from Origin or TS4. I don't know what do to.
