Meta Ray Ban suddenly unable to record video playing error sound with orange LED

Hey there,

I'm wondering if anybody else had a similar problem.

Whenever I want to start recording a video the "recording started" sound plays, but after ~4s the notification LED blinks orange 4 times & a "du-du-du" error-like sound plays through the speakers.
No video is recorded.

Photos still work fine.

I have factory reset the glasses, unpaired & repaired from the app. During the tutorial on repairing the video recording worked, but once I close the tutorial & try to record a video. Same behavior again.

Glasses & case are on 100% battery.

Anybody got some ideas on that?
