[2023] Cannot launch Warframe on Steamdeck or Linux [Investigating]

As others have suggested, temporarily setting Warframe to use "Experimental Proton" in its Compatibility settings for the Steamdeck may help you get past the point where the OS gives an error about virtual memory, and allow a normal update cycle to complete.  The game image on Steam has also been updated, so reinstalling from Steam would also fix that problem. 

However we're also working a DIFFERENT issue where the game may crash on launch because we're using a video setting not fully supported by the Steamdeck. Reinstalling or messing with Proton will not fix that, we can only ask for your patience and keep an eye out for hotfixes.
