Coult not write rx - glasses crash

[PixelSnake]

Hi there,

I am experiencing a strange issue. Sometimes after disconnecting and reconnecting to the glasses without turning them off in between, the following error message is logged to Logcat thousands of times, eventually followed by a StackOverflowException. Unfortunately I cannot reliably reproduce the error, sometimes it happens, sometimes it doesn't.

The biggest issue with this is that it crashes the glasses to the point where I am unable to turn them off by long pressing the power button. I tried holding the power button for a very long time (~10s) and eventually the glasses turned off but refused to turn back on. They can be reset by connecting them to the charging cable after which everything starts working normally.

Package name is replaced by xxxxxxxxx due to an NDA and for privacy reasons.
