I just started working with an arduino nano for some university work. I was able to get part of my project working when suddenly I started getting this error. I didn't change anything major, just an integer in my project. I was gentle with the arduino. I have tried it with other code and now nothing works. I am using ATmega328P (Old Bootloader) as the other one didn't work. I tried on a different computer and I got the same error.
If someone could help me get this back up and running it would be greatly appreciated.
EDIT: I am using a Nano 328 V3.0
