LP-EM-CC35X1: Matter lighting app demo becomes unresponsive

Part Number: LP-EM-CC35X1

Tool/software:

Hello,

I noticed that after running the matter lighting app demo for a while the CC35xx goes unresponsive in homekit and I see no additional logs printed to the UART console of the device.

This has happened twice and it seems like each time it has stopped after the same log message, but I see this message repeated throughout the application while it's running, so not sure what exactly I'm seeing that's an issue.

Attached are the logs from boot until crash. Any thoughts/ suggestions are welcome! Has this been seen before? I would say the demo was running for less than 30 mins, and my AP still registers the CC35xx as connected despite the demo being unresponsive and it's been several minutes.
