Any idea why this 544 B a.out was created and in my home folder? It was created at exactly 20:00:30.704776603.
At the time, I believe I was using Wine to launch Turtle WoW's launcher, switching between system wine and proton in Lutris, and possibly install webview2. The launcher did get stuck often so I killed it a couple times. Other than that, no commands around that time except for using pacman a few minutes later.
