avrdude done. Thank you.

OK, that is good. The blink after reset eliminates some possible causes of the upload error. We now know two things:
The primary microcontroller on the board is running
The bootloader program that handles sketch uploads is present on the microcontroller.
Now we move on to investigating other possible causes of the error.
This error might be caused by having the wrong port selected from the Tools > Port menu in Arduino IDE.
Please perform this experiment to verify that the port you have selected is your Arduino board:
With some boards, the port will be labeled with the board name in the menu (e.g., "COM42 (Arduino Uno)"). In this case, you can be fairly confident that you have identified the port. But for other boards the port will not be labeled. You can positively identify the port using this procedure:
Disconnect the USB cable of the Arduino board from your computer.
Select Tools > Port from the Arduino IDE menus.
Take note of the ports, if any, listed in the menu.
Close the Tools menu. The ports list is only updated when the Tools menu is re-opened, so this step is essential.
Connect the Arduino board to your computer with a USB cable.
Select Tools > Port from the Arduino IDE menus. - If a new port is listed in the menu, that is the port of your Arduino board.
Select that port from the menu and try uploading again.
If the upload still fails, or if no new port appeared after you plugged the Arduino board into your computer, add a reply here to let us know and we'll investigate the problem further.
It is possible for a short or external circuitry connected to the Arduino board to interfere with the upload process, causing this type of upload error.
Make sure the board is not sitting on anything conductive that could short the contacts on the bottom of the board. Make sure there isn't any conductive debris (e.g., strands of wire or component leads) on the board or on the surface the board is sitting on.
If you have a shield or any external circuitry or components connected to your Arduino board, try this experiment:
Disconnect the USB cable of the Arduino board from your computer.
Disconnect any shields, modules, external circuitry, etc. from your board.
Connect the Arduino board to your computer with a USB cable.
Now try uploading a sketch to the board again. Does the upload succeed?
This experiment will determine whether the upload error was caused by interference from your external circuitry. If so, you can then focus your attention on identifying the specific problem with the circuit and resolving it.
It was working normally and then it did not work, and now I have the same type of Arduino and it is working normally. I think the problem is in the driver or I donβt know.
If there was a problem with the driver, both boards would be affected.
The problem is most likely that you did permanent physical damage to the board by subjecting it to electrical conditions outside its rated limits. It is expected that anyone working with electronics will have a "magic smoke incident" from time to time.
I recommend you carefully review what you were doing with the board the last time it was in a working state. You may be able to identify the cause of the damage and in this way profit from the mishap by gaining knowledge that will allow you to avoid subjecting boards to the same conditions in the future.
Thank you. I spent hours on this issue. Your step-by-step was so very useful. I always feel like the use of comm ports on a pc is primitive technology. Anyway. Thanks for the thoughtful post.

Hi @gmk-1621. I'm going to ask you to post the full verbose output from an upload attempt.
This procedure is not intended to solve the problem. The purpose is to gather more information.
Please do this:
Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open.
Uncheck the box next to Show verbose output during: β compilation in the "Preferences" dialog.
Check the box next to Show verbose output during: β upload.
Click the "OK" button.
Attempt an upload, as you did before.
Wait for the upload to fail.
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.
Open a forum reply here by clicking the "Reply" button.
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.
Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the error output from the upload into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
