Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled.

hi,pschatmann.
@pschatmann
i am using the libraries of esp32-a2dp and arduino-audio-tools.
my board is esp32-wrover-e,and it have been enabled psram.
i want to use the esp32 to play the music from flash and bluetooth source.but when i start sending the stream from bluetooth after finish playing the music from flash, the esp32 will be crushed and show Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled.
but Strangely, it is normal operation when i play bluetooth music alone or play flash music.
here is my code and the crush log.
thx ^_^

`#include <Arduino.h>

I suggest that you analyse the stacktrace. This will give you the offending line...
ps. the psram is not used anywere in your sketch, so you can also switch it off.
The stop() is just running an endless loop to stop any further processing, so you should really decide what you really want to do
