Wine: RLIMIT_NICE is <= 20, unable to use setpriority safely causing fail start game

Yesterday it all worked fine, and last thing I did was opening the game in question, then closing it and shutting off the computer. Today, first thing I do after booting is starting the game - but it fails.
Noone touched the computer in-between and no updates has been done to the system nor the game.
Booted another computer with the same game installed, same issue all of a sudden.

Lutris is set to stable Wine-GE and the game has been working fine on both since I first tried it out about a year ago.

But now I get this:

Started initial process 41471 from gamemoderun /home/user/.local/share/lutris/runners/wine/wine-ge-8-26-x86_64/bin/wine /home/user/Games/genshin-impact/drive_c/Program Files/HoYoPlay/games/Genshin Impact game/GenshinImpact.exe
Start monitoring process.
gamemodeauto: 
fsync: up and running.
wine: RLIMIT_NICE is <= 20, unable to use setpriority safely
Monitored process exited.
Initial process has exited (return code: 1280)
Exit with return code 1280

So I tried a solution I found:
echo "* hard nice -20" | sudo tee -a /etc/security/limits.conf

Which resulted in:

Started initial process 2769 from gamemoderun /home/user/.local/share/lutris/runners/wine/wine-ge-8-26-x86_64/bin/wine /home/user/Games/genshin-impact/drive_c/Program Files/HoYoPlay/games/Genshin Impact game/GenshinImpact.exe
Start monitoring process.
gamemodeauto: 
fsync: up and running.
wine: Using setpriority to control niceness in the [-19,19] range
Monitored process exited.
Initial process has exited (return code: 1280)
Exit with return code 1280

The exit code bothers me here, usually anything other than 0 is bad.

All the above is using direct launch.
The log generated when using the official launcher is too long to include, which is what I normally use, but the reason for client failing is the same as above, and the launcher starts fine, clicking on “Start game” it minimizes as always - but instead of the game starting as it normally would, the launcher is back on screen. Thus tested direct launch as it generates less of a log to read.
Previously, launching directly has been working fine.

After this I tested other WINE-versions (ge-proton, ge-proton-custom, system) and they all fail to launch the game.
Tested turning off DXVK as I found a suggestion to do, didn’t work.

Note though I am using launcher version 1.4.2 and not 1.5.2 as the newer one doesn’t run.

That line about wine rlimit <= 20 is completely normal, I have it all the time
What I’m saying is, that isn’t what’s causing your game to crash, whatever is causing it not to run isn’t generating logs

but for that line I cannot install a game
