Apparently my Arduino Nano decides to not show up in either Tools > Ports or anywhere in Device Manager (there's no Other Devices and the "Ports (COM & LPT)" only shows my Arduino Uno that I have plugged in). I have the CH340 driver (the board is a clone) installed and I've checked my cable with my other Arduino Nano which did show up. It has also worked before with the same cable, which I had successfully uploaded sketches to it.
I'm using Windows 10, Arduino IDE 1.8.12, and the nano is a clone I bought off of Amazon.
I'm fairly new to forum posting so sorry for any lack of information.
