Hello,

No one can help you if you are not concise. What do you mean by "stuck in this condition"? There is no loop in HAL_PWR_EnterSLEEPMode().

What board are you using? Did you try this example https://github.com/STMicroelectronics/STM32CubeL0/tree/master/Projects/NUCLEO-L053R8/Examples/PWR/PWR_SLEEP ?
