1. THE ISSUE

"Steam" (Menu) and "..." (Quick Settings) no longer bring up the menu or quick start respectively. A hardware test shows both buttons work well.

I tried on my son's 256GB model and no problem on his, both buttons work.

1. HOW TO REPRODUCE

   Press the "Steam" button or "..." (quick settings) button.

   Nothing happens.

1. ADDITIONAL NOTES

A factory reset reverts the Steam client version to 1714854927 and solves this issue until a reboot automatically updates to Steam client version 1733265492 (Dec 3rd), and the issue reoccurs.

1. ADDITIONAL INFO (IF NEEDED)

SteamOS Version: 3.6.20

Steam Client Version: 1733265492
