this bug was brought to the stable client with 1766177208
fixed in today's beta (1767909714)
appears I spoke too soon. the option to eject the SD card appears if you insert the SD card while gamescope-session is already loaded, but if you start with the SD card in before gamescope-session starts, then you still cannot eject the SD card via the menu due to the missing options.
Seeing this as well on my Xbox Ally X on Bazzite. When I ran an older Steam version on my device the option was there, once it was updated the option to format or eject the drive is gone. (luckily I formatted the drive before I updated it) I am on 1766529085 steam version.
Nothing extracted yet.
