Hi @guswls6138. I'm going to ask you to post the full verbose output from an upload attempt.

:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

  1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
    The "Preferences" dialog will open.
  2. Check the box next to Show verbose output during: ☐ compilation in the "Preferences" dialog.
  3. Check the box next to Show verbose output during: ☐ upload.
  4. Click the "OK" button.
  5. Attempt an upload, just as you did before.
  6. Wait for the upload to fail.
  7. You will see a "Upload error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
  8. Open a forum reply here by clicking the "Reply" button.
  9. Click the <CODE/> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
    Code tags icon on toolbar
  10. Press Ctrl+V.
    This will paste the error output from the upload into the code block.
  11. Move the cursor outside of the code tags before you add any additional text to your reply.
  12. Click the "Reply" button to post the output.

In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here:

  1. Open any text editor program.
  2. Paste the copied output into the text editor.
  3. Save the file in .txt format.
  4. Open a forum reply here by clicking the "Reply" button.
  5. Click the "Upload" icon (Upload icon) on the post composer toolbar:
    Upload icon on toolbar
    A dialog will open.
  6. In the dialog, select the .txt file you saved.
  7. Click the "Open" button.
  8. Click the "Reply" button to publish the post.

Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.
