Can not use PIO Debug, STM32L476/freeRTOS/?

Hi,
I cannot use the pio debug once I enter in, it always in the CopyDataInit, even I click many times the RUN(F5), what happened?

In the left side, the only breakpiont that is set is in startup_stm32l476xx.s. You can try and set a breakpoint in e.g. setup() and then press ‘continue’?

that has no effect, even I delete all the breakpoints, the code is always run here, but with out debug mode, it can run correctly .
