I'm experiencing an issue on Dauntless when running it on my Steam Deck. It's very similar to this post: 🆘-supportDauntless HELP
There are two things of note: 1. A message pops up before reaching start menu reading "EasyAntiCheat hash catalogue not found." 2. After pressing "Ok", I'm at the start menu. After hitting play, I get the following error message after waiting for a bit while the game attempts matchmaking: "A network connection could not be established. Please check your network connection."
