zephyr: STM32WB55 Bus Fault when connecting then disconnecting then connecting then disconnecting then connecting

STM32WB55 Bus Fault when connecting then disconnecting then connecting then disconnecting then connecting. I’m using nRF Connect for Mobile to connect to the STM32WB55. Referenses:

After the last Connected using nRF Connect for Mobile it fails to connect.

Modifying the prj.conf like removing CONFIG_BT_BAS=y can stop zephyr log from printing the BUS FAULT but still after 3rd connection the nRF Connect for Mobile will refuse to connect to STM32WB55.
