I'm new to Linux, using Kubuntu. I got Left 4 Dead 1 installed from Steam and I'm using Proton 8.0. I get an error saying "An error occurred while launching this game: invalid app configuration". Is there a launch option I should be using? Something else?

Try cycling through other proton versions as well. I don't really understand why some games will work on older versions and not newer ones, but it happens.

This is what worked. I had to go down to version 4.2-9 and it finally ran.

Just had to find the right magic spell 🙂
