Sub-GHz and ADC DMA integration errors

Hi All,
I'm using STM32WL55JC board which include Sub-GHz, ADC and DMA peripherals (and many more of course)
I run "ping pong" example to create Sub-GHz communication sucssfully, also run "ADC_SingleConversion_TriggerTimer_DMA" and changed to circular mode (DMA) I saw buffer changing variables according to ADC result.
I configured ADC and DMA at "ping pong" example exactly as they configured at ADC example, and start via HAL_ADC_Start_DMA() command the buffer result is written only once, then program start Sub_GHz routine of RX-TX and the buffer results stuck and doesn't change.
what can be the reason?
adding some pictures from ping-pong - ADC DMA configuration
I'll appreciate your help!
