Quest 3 (v81.1034) randomly cannot access the user profile menu after waking from sleep

I have some sort of random glitch when the Quest3 headset (v81.1034) wakes from sleep. Sometimes it only shows passthrough, and the menu to select which user profile to use does not appear.

If I press the sleep button a few times, the profile menu appears for a fraction of a second and then disappears and goes into passthrough mode again. So, when this glitch occurs, I am unable to select my user profile to log in to the Quest 3.

If I double-tap the headset to exit passthrough, it tries to load my new Immersive Home but fails to load because I have not been able to select any profile, so it gets stuck in load screen limbo:

From here, all I can do is restart the headset, which fixes the problem temporarily. This glitch has happened 3 times in the past 3 days since getting the V81.1034 (non PTC) update on 21 October.

I've already reported this glitch to Meta via the headset bug reporting option.

UPDATE: the glitch happened again just now. I pulled the headset away from my face slightly and noticed that the user profile menu reappeared. As soon as I put the headset closer to my face, the passthrough came back on and the profile menu disappeared. I was able to hold the headset slightly away from my face and click on my user profile using the controller. Then the headset started up as normal and my Immersive Home loaded. It seems like some sort of glitch in the way v81 uses the proximity sensor when waking from sleep.
