Getting Null as output no matter using serial communication!

oh hey there thanks for the reply forgot to add the platform.ini
here it is

[env:denky32]
platform = espressif32
board = denky32
framework = arduino
monitor_speed = 115200
monitor_rts = 0
monitor_dtr = 0 

btw i saw a previous thread (Noob stuck on ESP32-CAM+MB with PIO/vscode)
so therefore added the two lines below but no luck ( still having same issues)
