Hello @herbzhao, this issue reads like a problem with the Steam client instead of SteamOS as a platform, so I've transferred this issue report.
Hello @herbzhao,
I assume this doesn't go away if you restart or reboot?
Have you tried switching to the beta Steam Client (Settings -> System -> Steam Client Udate Channel)? Any software customizations you've made to the device that we should know about?
Hi @TTimo I fixed the problem by check the enable "steam play" in the developer options. Not sure why I unchecked it, I may have misread it as steam play everywhere which I don't use.. This options probably shouldn't be allowed to be ticked off on steam deck.
Nothing extracted yet.
I am using my steamdeck, and today suddenly most of my games become unplayable.
Steam thinks my game are not installed while they are installed (whether on SSD or SD).
And I have no way to uninstall the game now.
