Tried targetExe override, Legendary update, launcher reinstall. Game attempts to open but does not even appear on Task Manager for whatever brief period of time it would be up.
I had an issue launching on my steamdeck and changed the Wine Version to Proton - Proton 8.0 from the default Wine-GE-Proton8-27-Lol under settings and that fixed my issue.
Thanks for the tip, it doesnt seem to be installed and the options avail were default on initial install. I will pull it down and use it. I never even looked at those configs untill I was having issues with this game
