Zephyr mesh shell crashes during provisioning

Question

I added a mesh shell module to my firmware running on nRF52480 .

Opened the mesh shell

uart:~$ mesh init
Mesh shell initialized

mesh provision 0 0x100 0

Crash (see below)

proj.conf configured as follows

CONFIG_BT_MESH_SHELL=y

CONFIG_BT_MESH_CFG_CLI=y

CONFIG_BT_MESH_HEALTH_CLI=y

CONFIG_INIT_STACKS=y

CONFIG_THREAD_STACK_INFO=y

CONFIG_HEAP_MEM_POOL_SIZE=8192

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=8192

CONFIG_BT_RX_STACK_SIZE=4096

CONFIG_BT_MESH=y

CONFIG_BT_MESH_RELAY=y

CONFIG_BT_MESH_FRIEND=y

CONFIG_BT_MESH_ADV_BUF_COUNT=13

CONFIG_BT_MESH_TX_SEG_MAX=10

CONFIG_BT_MESH_PB_GATT=y

CONFIG_BT_MESH_PB_ADV=y

CONFIG_BT_MESH_GATT_PROXY=y

CONFIG_BT_MESH_PROXY_USE_DEVICE_NAME=y

CONFIG_BT_MESH_ADV_STACK_SIZE=2048

Any ideas?

It would be really helpful if there was a guide with memory requirements for various buffers used by the mesh stack

Thanks
