Calling k_event_post from Interrupt context in zephyr RTOS

Question

Hello All,

I am using RTC interrupt handle on the NRF5340 kit to set the event using k_event_post API from the interrupt context and when I try to wait on this event in the main function using k_event_wait it is never set the event and when I tried to debug using the NRF5340 kit debugger it works using the debugger but when the NRF controller run in freerun mode it didn't work.

and here is the example I am using to test this scenario.
