Optimizing ambient battery airflow, verifying braided cable locking collar engagement, and power-cycling.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

1. Ensure the aluminum battery pack is resting on an uninsulated surface with free ambient airflow (not inside pocket).
2. Verify the braided tether connector is firmly locked: align white dot on cable with white dot on audio strap, insert, and rotate clockwise 45 degrees until yellow dot disappears.
3. Reboot Vision Pro by holding both the Top Button and Digital Crown until the Apple logo appears on EyeSight display.

Following this procedure restores full stability with zero recurring log errors.
