Mayby some usefull thing, lutris from repo can be usefull with the hacks of thinks donr work. For some games some settings to play optimal. You have also playonlinux but i dont know its known by them, it can runnseveral wine version, one of those works
I reinstalled lib32-mpg123 and wine. But i don’t understand what you mean with "Try also installing … I have indicated to you … for 32bit libraries. @ricklinux i checked the setting of multilib again and multilib is already enabled. I enabled multilib-testing now, maybe this is what it wants.
Now Lutris is starting, i can push the play button on Epic Games, but after start the button goes to stop and then back to start.
I’d recommend searching the Lutris forum. I had a similar problem a while back and it turned out to be a too old dot-net-framework. Tinkering with Winetricks and changing the wine-prefix in the Lutris menu finally helped.
