whyy i need help

Please enable verbose output during upload and disable verbose output during compilation under file/preferences, perform an upload and post the results here (using code tags as described in https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966#use-code-tags).

Did it work in the past? If yes, what was the last project that you were working on when it started failing?

If it never worked,

  1. There are three options under tools/processor; try all three of them.
  2. Is you Nano an original or a clone? Can you provide a link to what you bought?
    A clear picture that will allow us to identify the chip on the top (should say ATmega328P) and one of the chip on the bottom (either FT... or CH34...) will also help.

I doubt that was all output. And it's not presented using code tags.

This is the typical output similar to yours

avrdude done.  Thank you.

And please answer the questions in my previous post.
