hal_delay() not working

PPopo.1

So I've created a project and am trying to use the HAL_delay(10); but it gets stuck at this function when im trying to debug.

I have been changing the clock and enabling the TIM2 so I don't know if i've messed something up. Here are the settings that I have:

And that is about it

could be some issue with HAL_GetTick?

so this is the inside debug of delay:

Make sure SysTick_Handler() is calling HAL_IncTick(), that it's not weak, and that it is binding into the image.

Double check SCB->VTOR pointer to your Vector Table address, and that the interrupts aren't disabled.

seems: sysclk not running ...because tickstart should not stay at 0.

should be so: (> 0)
