STM32CubeMX project created ADC LL lib problem

I had used STM32CubeMX generated ADC with STM32H750VBT6:
ADC_REG_InitStruct.TriggerSource = LL_ADC_REG_TRIG_EXT_TIM1_CH1;
ADC_REG_InitStruct.SequencerLength = LL_ADC_REG_SEQ_SCAN_ENABLE_2RANKS;
ADC_REG_InitStruct.SequencerDiscont = ENABLE;
ADC_REG_InitStruct.ContinuousMode = LL_ADC_REG_CONV_SINGLE;
ADC_REG_InitStruct.Overrun = LL_ADC_REG_OVR_DATA_PRESERVED;
LL_ADC_REG_Init(ADC1, &ADC_REG_InitStruct);
->but ADC not working.
My modify:
ADC_REG_InitStruct.TriggerSource = LL_ADC_REG_TRIG_EXT_TIM1_CH1;
ADC_REG_InitStruct.SequencerLength = LL_ADC_REG_SEQ_SCAN_ENABLE_2RANKS;
ADC_REG_InitStruct.SequencerDiscont = LL_ADC_REG_SEQ_DISCONT_2RANKS;
ADC_REG_InitStruct.ContinuousMode = LL_ADC_REG_CONV_SINGLE;
ADC_REG_InitStruct.DataTransferMode = LL_ADC_REG_DMA_TRANSFER_UNLIMITED;
ADC_REG_InitStruct.Overrun = LL_ADC_REG_OVR_DATA_PRESERVED;
LL_ADC_REG_Init(ADC1, &ADC_REG_InitStruct);
-> Issue had'nt fixed.

I change to HAL lib with ADC1


hadc1.Instance = ADC1;
hadc1.Init.ScanConvMode = ADC_SCAN_ENABLE;
hadc1.Init.EOCSelection = ADC_EOC_SEQ_CONV;
hadc1.Init.LowPowerAutoWait = DISABLE;
hadc1.Init.ContinuousConvMode = DISABLE;
hadc1.Init.NbrOfConversion = 2;
hadc1.Init.DiscontinuousConvMode = ENABLE;
hadc1.Init.NbrOfDiscConversion = 2;
hadc1.Init.ExternalTrigConv = ADC_EXTERNALTRIG_T1_CC1;
hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_RISING;
hadc1.Init.ConversionDataManagement = ADC_CONVERSIONDATA_DMA_CIRCULAR;
hadc1.Init.Overrun = ADC_OVR_DATA_PRESERVED;
hadc1.Init.LeftBitShift = ADC_LEFTBITSHIFT_NONE;
hadc1.Init.OversamplingMode = DISABLE;
hadc1.Init.Oversampling.Ratio = 1;

it working, issue is fixed
Thanks.
