Trouble with uploading to arduino nano

Development Tools Uploading
1

I am new to Arduino and this is my first project. I order an arduino nano off aliexpress (most likely a knockoff) and I am having trouble uploading code to it from arduino IDE 2.3.4

This is how I have things currently set up. I need to get this project done as soon as possible so any help would be appreciated

Do you have the Serial Monitor open? Or does any other program have COM4 open?

If this happens to me, I reboot the computer & this usually fixes it.

What board did you select and bootloader

Does COM4 disappear from the IDE (and Windows device manager) if you disconnect the board from the PC?

What happens in Windows device manager when you connect the board? Any yellow triangles?

As you have a clone

  1. You probably have to install the CH340 driver; did you?
  2. You probably have to select one of the other options under tools / processor in the IDE. This will not solve the "Access denied problem".

For any connection issue I'd suggest you try one of these tools first.

Starting with the basics.
Does your sketch compile without error?
If so, show the full error report after enabling the verbose option.
If not, show your sketch in full, as text.

And in either case, show exactly how you’ve wired your Nano. A careful drawing or schematic plus a clear photo would be good.

That error is mostly due to a wiring error, but not always.
