This is not in the main aurora folder. The Global Settings.json that you are referring too is created when aurora is first opened. This is roughly in the %appdata%\Cheat Happens\Aurora area. This issue is with proton and HGL this is created in the Wine Prefixes folder that is created on a per game basis. It would need to be a setting in the main aurora folder to make it so we would not need to configure it for every game manually so changing the setting in that json could help if you cannot get it to load fully to get to options to toggle it off, but we would still have to change this setting for every single game.

I guess I am just not understanding the issue. You said you wanted an option in a text file so that Aurora always starts with hardware acceleration turned off. That is exactly what the "EnableHardwareAcceleration": false, line in the Global Settings.json file does.
Are you saying that on the Steam Deck this .json file gets created in a different folder per game?
