M5GO firmware v0.1.6 aborts with GUIDE screen

inachi

I recently updated the M5GO firmware to v 0.1.6. This version has the problem that MicroPython suddenly aborts. This problem is reproduced by leaving M5GO on the GUIDE screen and leaving it for ten or more seconds.

The following is the serial output when an abort occurs.
