Hi @amishapatel4966. I'm going to ask you to provide some additional information that might allow us to determine the cause of the problem.

:exclamation: NOTE: These instructions will not solve the problem. They are only intended to gather more information which might provide a clue that eventually leads to a solution.

Please do this:

  1. Select File > Preferences from the Arduino IDE menus.
  2. Check the box next to "Show verbose output during: ☐ compilation".
  3. Click the OK button.
  4. Select Sketch > Verify/Compile from the Arduino IDE menus.
  5. After the compilation fails you'll see a button on the right side of the orange bar in Arduino IDE: Copy error messages. Click that button.
    This copies the full output to the clipboard.
  6. Open a forum reply here by clicking the Reply button.
  7. Click the </> 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 block
  8. Press Ctrl+V.
    This will paste the compilation output into the code block.
  9. Move the cursor outside of the code tags before you add any additional text to your reply.
  10. Click the Reply button to post the output.
