I couldn't lunch the game sims4

memory is NOT hard disk space. you might be running out of ram. if you are in windows 11 you need at least 8 gbs of RAM to run the game. more is better.

I have windows 11 and 8GB of RAM 

remember from those 8 gbs of ram about half is used by windows so you actually have 4 gbs for the game. that is what the game needs just to boot a 30x40 lot. i would sugget getting 16 or better 32 gbs of ram if you can. i do own a MSI gaming laptop and did the same as well. whent from 16 to 32 gbs.

it's using 7.82GB plus I played it already for 114 hours before this issue

olchaos  32 GB RAM is wildly unnecessary for Sims 4 unless you plan on running multiple demanding apps alongside the game.

puzzlezaddicti never said the game requires 32 gbs. i mentioned i had 16 gbs was running low for me and double it up to 32 gbs. i do play games like forza horizon 5 or horizon forbidden west that uses 10 gbs of ram just to run, plus windows that uses between 2 to 4 gbs on its own. then again that is my setup. my suggestion was DOUBLE your RAM. not "get 32 gbs of ram or sims 4 wont run" but i do appreciate the attention to details and that you mentioned me VS do a generic reply.
