When I burn the code of play_mp3 again, it shows coder init failed. What is the reason for this? Could you please help me?

I renamed your post, as 'can everyone help me' is not that useful. What hardware are you using? Did you modify anything on the board, or connect anything to it?

I used esp32-lyra and I ran "hello world" once before.
