"An error occurred while uploading the sketch"

what can i do?

Hey,
enable "Show verbose output during" upload and send back the console output.
Please format the output as code.

Go to: Arduino IDE > File > Preferences > Show verbose output: Select both options: "Compilation" and "Upload". Then try to upload the Blink example (Arduino IDE > Files > Examples > Basics > Blink) and please send to us the copy of the whole text shown in the console.
