Error when trying to launch Northstar on Debian Trixie.

[obsidianyeen]

After installing Titanfall 2 via Steam, opening then closing the game, launching Northstar, then pressing "Launch", I get an error message that reads

Not yet implemented for "linux" with Titanfall2 installed via "UNKNOWN"

even though I have installed Titanfall 2 using Steam.

Steam installed via apt through contrib
sudo apt install steam-installer -y

Which proton version are you using?

Having the same problem on CachyOS, tried Cachy's own proton, proton experimental, hotfix, and GE-Proton10-33. Oddly enough, it originally worked with whatever proton I tried without errors, but then I tried Viper, and then switched back to FlightCore and this started happening (I fully reinstalled the game and deleted any FlightCore / Viper related folders I could find).

If it's relevant, I'm also running KDE Plasma.

Does the "Launch Northstar via Steam" dev option work?

[Xephyrose]

Just tried that, it oddly says "Titanfall2 was not installed via Steam". Earlier when I tried to use flightcore, it'd just say "Failed to launch Titanfall 2 via Steam" if I had "Force the use of a specific steam play compatibility tool" disabled, but after reinstalling the game and retrying, it consistently says "Not yet implemented for "linux" with Titanfall2 installed via "UNKNOWN"" unconditionally.
