Panic, when playing music

Hi

I have build a sample project nRF5430_audio for nRF5340 Auido DK(two DK, one for gateway, one for headset), following the guide:nRF5340 Audio — nRF Connect SDK 2.0.99 documentation (nordicsemi.com)

build the project: 

python buildprog.py -c both -b debug -d both -p

add following to prj.conf
CONFIG_SW_CODEC_SBC=y
CONFIG_AUDIO_SOURCE_USB=y
CONFIG_TRANSPORT_CIS=y

after streaming for a while,the headset will panic:
HL [00:08:42.849,517] <wrn> audio_datapath: Invalid sdu_ref_us delta (9983) - Estimating sdu_ref_us

HL [00:08:53.321,960] <err> error_handler: Caught system error -- reason 3. Entering infinite loop 

so, i think there is a bug, is any patch for it?
