I am using the stm32g473mbt I generate a project with cube mx I only confirm the communication with the 5-pin jtag, from the main I read Systiks timer, with the library running_boot1 = HAL_GetTick (); i the reading is always 0

If SysTick isn't being called, perhaps you have interrupts disabled. Hard to know what's going on without any code.

Has this function been generated by MX: SysTick_Handler()

It calls HAL_IncTick() which is the counter returned by HAL_GetTick()

Should be enabled in MX:

Pinout & Config > System Core > NVIC > NVIC > Time base > Ensure its enabled
Pinout & Config > System Core > NVIC > Code Generation > Time base > Ensure [Generate IRQ Handler] and [Call HAL handler] are enabled
If they aren't all enabled try to figure out how that happened, as I think these are enabled by default in new projects.
