arduino - Issues Flashing STM32F401CC with CubeProgrammer DFU

Question

I'm trying to do a DFU program upload via Arduino for an STM32F401CC. I'm using CubeProgrammer to upload the compiled bin and verify the contents of the STM32's flash is being written starting at 0x8 -- it's all there. I'm using a jumper to pull B0 high and am verifying it shows as STM32 BOOTLOADER in the device manager, then I'm disconnecting it. Everything shows that the program is upload correctly, but my program isn't actually running (make onboard PC13 LED blink). I'm using a board I got off amazon but verified the STM32F401CC is genuine. Is there something I'm missing? I'm coming over to ARM after years of using the ESP32.
