It is possible to run the game from desktop mode with the least amount of drawbacks. Running from game mode isn't recommended as of ver. 2.4
Initial pop-ups and login UI elements might block the screen, might shown as black screen on initial launch from steamOS mode. This issue can be mitigated by running in desktop mode.
there's no option for scaling resolution in fullscreen mode
There's a white pop-up that like to cover the screen. It has no content and only have two options "accept" and "cancel" in chinese. They both doesn't seems to to do anything when you click on it beside repeatedly reopen. However, there's a black pop-up box that cover the screen after you finish logging in that impossible to remove on steamOS mode. This does not seems to be an issue on desktop mode. I suspect it might be related to the initial pop-up
Keep in mind, as of version 2.4, Kuro Games is still trying to make the game compatible on Steam Deck. While the game can be run without anti-cheat blocking the game as from the latest version, there's still a lot of UI issues that needed to address before it can fully run on steamOS mode

The game works on the Deck, but not on Linux desktop PCs

Game refusees to boot. Waiting on devs to add Steam Deck support

Able to login via username/password, but kicked out of the game after loading in due to anti-cheat module.
kuro games is apparently working on steam deck compatibility, hopefully soon.

but they are adding support to the Steam deck

The game lets you in on Steam Deck for the main menu, ACE kicks you out when entering the actual game

dead game, doesn't work on Steam deck, I tried using different protons with no result. Previously had to install the Windows to run. I expected that the release in Steam will fix the situation, but alas
