v85/v2.1.1034 Passthrough Loop

I put this on Reddit also posting here in case it's a bugged update?

Ok so this is my issue after Feb 27th v2.1.1034 Update:

1. The Problem: v85/v2.1 "Passthrough Loop"

AI advises: This specific flickering issue (cycling between Home and Passthrough) is a known bug associated with the v85/v2.1 update. It appears to be tied to a conflict between the new "Navigator" UI and the headset's tracking/boundary service.

Why it happens: The OS is essentially "crashing" the immersive home environment and falling back to Passthrough as a failsafe, then attempting to reload the environment again.

The "Double Tap" Fix: Manually forcing Passthrough works because it tells the OS to stop trying to render the immersive environment, which bypasses the crash loop.

2. Process: Meta Software Update Tool

Attempted resolution: I proceeded with the Sideload Update - update successfully loaded but....

Issue persists > Goto 1. LOL.

So right now I will perhaps await the next meta update which may fix my problem before attempting a factory reset and linking accounts up etc...

> If I manually enable pass through, I can get to quick access menus etc. so could update from there when next update available.
> I haven't tried - PC Wired Link yet, so hopefully can get to MSFS SIM I use.
> For the moment, standalone usage is a no go.

Note:
> I do have WhatsApp on the Quest which I know is active and in past updates I've seen this crashing in the background via notifications message things popping up. That has not happend this time but I think the Q2 may be struggling in my case as per above, something is causing it to crash.

> I recently starting testing the 3rd party Immersive App on Q2 with it's version of remote desktop and virtual second monitor feature it can use with a laptop, as native Meta RD can't do that.....but I'm assuming nothing is running in BG with that app if it's not being used......

META / Anyone - any thoughts?
