Please do this:
  • Close all Arduino IDE windows.
  • Start the Arduino IDE.
  • Tools > Board > Boards Manager
  • After you get the error message, click the "Close" button.
  • Click on the black console window at the bottom of the Arduino IDE window.
  • Press Ctrl+A to select all the text.
  • Press Ctrl+C to copy the selected text to the clipboard.
  • Paste the copied text into a reply here, using code tags (</> button on the toolbar).


That might provide some information that we can use to help you.
