nRF5340+nRF7002: Random crashes on Matter certification tests TC-RR-1.1 and TC-OPCREDS-3.1

Hi, 
We are using nRF Connect SDK v3.0.2 (Matter 1.4.1)
We are trying to do Matter certification, but we have an issue on TC-RR-1.1 and TC-OPCREDS- 3.1
The device crashes randomly at around middle to end of the test (around 40 to 60 seconds into the test). The test is run individually.
Please see sample logs going into the crash:
