Why doesn't the ADC work when I select the prescaler ratio "HRTIM Clock Multiplied by 32" for the timer that triggers the ADC?

HelloI use a HRTIM timer (Timer B) to trigger the ADC (ADC2_IN5) internally (STM32G4).I want to increas the high-resolution clock frequency fHRCK with a prescaler ratio: 170MHz*32=5.44GHz to trigger the ADC via a compare value of 54.400.Unfortunately...
