illegal state in lorawan process stack crash - v4.5.0

[cmorganBE]

stack v4.5.0, esp32 port (internal at the moment)

I'm seeing this crash 306s after startup:

INFO: smtc_modem_run_engineI (306875) smtc_modem_hal: disable_modem_irq
I (306875) smtc_modem_hal: enable_modem_irq

 Start a new join sequence now on stack 0
I (306875) LoRaWAN: Modem event callback
W (306875) LoRaWAN: Event received: JOINFAIL
I (306875) LoRaWAN: attempting to join again
INFO: smtc_modem_join_network

I don't believe it is related to stack overflow as I have stack checking enabled in esp-idf.

Thoughts on how to debug? I'm getting more familiar with the stack every day but still early in understanding it fully.

Also, I see radio IRQ during the porting tests (which pass), but for whatever reason not during my relatively simply use case of joining. Timer irqs are occurring and look to be working as expected.

Hi,
In a first step, could you please check and confirm you are using the same HAL for porting tests & your application ?
Thank you very much,
Best regards,
