Can't upload code to Nano

Official Hardware Nano Family Classic Nano
1

Hey, as title says, I cannot upload to my Nano, but can upload to 5 or so Uno's and a Mega, I followed the other posts instructions, but I don't know much about arduinos in general.
Here's a list of things I did.

Windows 10

Installed CH340
Back of Chip says FT232RL, didn't know how to check if I have a clone before installing drivers.
Installed FTDI drivers,
Tried different USB port, not different cable. Cable says "high speed data", and was brand new (opened last night).
Updated the AVR Boards to 1.8.6 (but also tried prev version and a random much older one.
Arduino was on version 2.0.3 (afaik, previous to 2.0.4) updated to newer version (2.0.4)
Before Updating IDE I didn't get any board info, now;

Lists the port as 12, when I unplug it disappears.
Device manager shows the device as USB Serial Converter

Currently trying to upload code using old bootloader and it uploads forever, but TX pin is flashing.
New bootloader gives this error code (did not give this before IDE update).

Any help appreciated!

Why do you think that the upload using "New Bootloader" is a failure ?

avrdude done.  Thank you.

Looks OK to me

I was using the "show verbose output" which i've never used before. Was using a bare Arduino with no pins so I assumed it was an error, re-plugged everything and it works! All those hours just to find its the IDE version :face_holding_back_tears:

Thank you though, never would have figured it out it was working now hahaha.

A simple test is to upload the Blink example. If the LED blinks then the upload probably worked. To make sure, change the delay() interval and upload again to make sure that the blink rate changes

Hi,

Sorry to bring up the issue again after marking as solved, it worked when I replied, but the day after it stopped. I decided to leave it, as I went to my University to try the Nano on a different computer to see if the issue was my PC, and it worked fine. So know I'm not sure, do you have any idea why it might be my computer specifically? Obviously, my Uno's work completely fine, so I'm just going to use those and then transfer everything over when I'm done in the lab. But it is a pain. And over this semester I've worked a lot using Arduino and I really enjoy it, I'd like to use more Nano's for cool things in the coming months, so any suggestion on a potentional solution would be great!

Also worth noting, I am using RF and realised sometimes uploading new code does not actually upload it and I've had to reset it (both UNO and Nano) but resetting only worked for my Uno's whereas obviously with my Nano this issue occurs. Some people have mentioned that simply resetting it and then uploading fixes it. I'm using my Nano for RF transmission. But as advised I've tried both Blink and LCD code but that still fails to upload. Is there any pins (except hardware serial 0/1) that I should avoid using?

Here's the error,

avrdude: ser_open(): can't open device "\\.\COM12": Access is denied.


Failed uploading: uploading error: exit status 1

Again, thanks for any help.

Edit: The Arduino version in my University is over 2 years old. However, all the code was written at home anyway as the older version only allows use of one serial monitor simultaneously which Is obviously annoying.

Edit2: Tried another Nano and same issue but on COM13
Error code;

When using IDE 1.8.x if you open 2 or more instances of the IDE rather than opening one then doing File/New then each instance can use a different COM port and/or board, if that is what you mean
