how to use dual simultaneous adc with DMA

[DEska.1]

So I Am trying to use the dual regular simultaneous mode with DMA transfer, I tried to use one ADC with the DMA transfer and It works fine but with 2 ADCs I use the function HAL_ADCEx_MultiModeStart_DMA() but the called back function is not actually called so the HAL_ADC_ConvCpltCallback() is not called which means no conversion is happening also the buffer is empty

does anyone have any idea how to fix that?

here is my main.c code:
