Computer Freezes While Playing Sims 4

Do you have any programs running in the background when you play The Sims? Especially graphics programs, such as those used for screenshots.
Close all such programs that you do not need to use during the game.
Check if your Windows is up to date

Perform a clean boot of your computer

However, the most likely cause is some program running in the background what conflicts with the game.
Of course, the reason can also be very simple. Poor ventilation, because the computer was not cleaned for a long time, can also give such an effect.
