<![CDATA[M5 Stick C : "Guru Meditation Error: Core 0 panic'ed (LoadProhibited)"]]>Using Arduino 1.8.12 , Library: M5StickC 0.2.0

My M5Sticks run anywhere from 2days to 3 weeks and then crash.
The crash typically happens right after some WiFi networking call.
For example:
crash after: http.begin(g_wClient , g_cHttpCmd);
or crash after : iRSSI = WiFi.RSSI();

After the crash, the M5 Stick C does not automatically reboot , which I believe it should

Attached is the debug output:
