Too many open files error - Steam Flatpak Linux.md

Solution to copy & paste on the Terminal

flatpak override --user --env=PROTON_NO_ESYNC=1 com.valvesoftware.Steam

Explanation

I tried to play World of Warships on Clear Linux using the flatpak of Steam, but the game never started. So, I ran flatpak run com.valvesoftware.Steam on the Terminal to see if there was any useful information. The error that called my attention was eventfd: Too many open files. I did a google search and found some mention about setting PROTON_NO_ESYNC=1 as an environment variable. So, I ran flatpak override --user --env=PROTON_NO_ESYNC=1 com.valvesoftware.Steam on the Terminal, to set the environment variable PROTON_NO_ESYNC=1 for com.valvesoftware.Steam. I tried again and it worked.

Thanks, @smcv. I appreciate the comment.
It's been a while since I used Steam, but I don't remember why I didn't choose the solution you mention which I remember it was suggested somewhere. Maybe I read about the suggestion of the soft limit instead of the hard limit, I'm not sure.
