After the main blink loop starts, probe-rs not working

I placed a blocking loop before the main loop and able to flash it by pressing NRST button

```
for _ in 0..8_000_000 {
cortex_m::asm::nop();
}
```

(I originally tried with RPi debug probe then bought cheap ST link programmer)

Debugging Hardware 😵‍💫

Not able to flash STM32 with probe-rs

Is it code or config? No
Is it probe-rs version? No
Maybe udev rules ? No
Wiring issue? No

Took 2 days and finally got kind of lead

----

After i flash embassy blinky, not able to flash it again

If i flash stm32f3xx-hal, it is fine

Just watched a video short(AI generated I think) referring to ESP32 as "E S P 3 2" (Three Two) 😶

Do you pronounce it as "Thirty two" or "Three Two"?
