This morning, I ran
sudo pacman -Syu as usual, which among other things updated also Lutris. After the update was done, Lutris just wouldn’t open. There were no error messages during installation, it all seemed normal.
I tried uninstalling
sudo pacman -Rs lutris, and reinstalling all dependencies listed in the Arch Repository and then Lutris itself. It does appear as one of the installed programs in my system, and right after I click the icon to open it, a window opens and shuts down a split-second after.
Would you please help me solve this? I’m considering reformatting the OS, even though it feels like an overreaction.
