Arduino pro micro code running troubles

Community Suggestions for the Arduino Project

hello everyone
so i've recently obtained an aruino pro micro (the 16mhz edition)
i've managed to get it connected to my laptop and get the port automatically read through the arduino IDE.
i've tried afterwards the typical blink code, the IDE gives me a "upload complete" message but the the LEDs are frozen and the code isn't functional
i've tried tweaking the blinking code but it's not working.

the output widow as follows:

Posting the code that doesn’t work is a good first step, since your upload was successful.

You are aware that the Pro Micro does not have a built-in L-LED? So the blink example does not have any visible effect. To blink the onboard RX/TX LEDs, see https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide/all#example-1-blinkies

FYI
There is one setting in the IDE (File → Preferences) that you can enable to make sure that the data is correctly written.

the simple adjustment was just in the delay values to see if there's something different. no big changes

thank you for your help. it was my bad in recognizing the type of LED
i tried the serial led blinking code and it works perfectly
