Symptoms
The games launch and I get decently far. However, as soon as the game tries to connect to a server and checks for whether EAC is running, I get an error saying that it's not running.
I have had the same problem with other EAC titles in the past (Armored Core 6 and The Finals) but Lost Ark and Killing Floor 3 are the two most recent ones which I really want to play and I have no idea what else to try or where else to ask for support.
Note that I do see the EAC window for a few milliseconds upon launching a game.
I have tried Steam Flatpak but got the same error.
I also tried it after installing glibc-eac but still the same error.
Reproduction
I don't know honestly. >Be me?
