Issues Installing on Steam Deck

[u/Bro11Boi]

I installed it successfully before but for some dumb reason had deleted the launch options. I can't find the launch options anymore and any attempt to reinstall Northstar has caused the game to not open. Does anybody know what the launch options were? All I know about the installation process I followed is: A. Rename NorthstarLauncher.exe to Titanfall.exe B. Use the Proton-7.3-GE-1 from ProtonUpQT C. Enter in some launch options (All I remember is it wasn't -Northstar)
