EAC Seems broken on Arch?

I recently installed BattleBit Remastered on Steam (uses EAC). Upon trying to run the game, I only get as far as a screen telling me to ensure EAC is installed. I tried their "repair EAC" option in steam, and there was no change (a terminal opens, blinks, and closes again). I tried a system update to see if that would help, but no dice.

Now, when I try to launch Apex Legends (a game which I play all the time), I see EAC loading extremely slowly, then it goes away, but the game never launches (though Steam still shows the title as running).

Is anyone else having issues right now (with an up to date system)? Has anyone else experienced this before?

Edit: Decided to format my OS drive and move to Fedora. Using the same steam library, both games are now working. Clearly some package ended up misconfigured, but I have no idea what or why.
