Esync limit won't change

Question

I installed Lutris with Wine to play games on my Linux computer but I'm encountering an issue with Esync which is required to play the game I want. So I tried everything on both those links : https://github.com/lutris/docs/blob/master/HowToEsync.md and https://github.com/zfigura/wine/blob/esync/README.esync (I am in the systemd case but I also tried the other one). But whatever I do ulimit -Hn will always return 4096 and Lutris won't enable Esync. Does some have an idea on how to fix this ? I don't know what else to do about that. Thanks.
