Having issues uploading to my arduino nano

Development Tools Uploading
1

Hi,
I am was working on a project for my upcoming 2 year anniversary and it was all going good and my code was getting uploaded correctly until a few days ago. My code refused to get uploaded to my arduino nano. I noticed that deleting recently downloaded libraries could fix the issue so i did that but the problem persists. this is my error message:

exit status 1
Error compiling for board Arduino Nano.

its super frustrating as its short and not descriptive. i do see some other red lines of text so ill include them here too:

C:\Users\Adrian\AppData\Local\Temp\cc2q1JXv.ltrans0.ltrans.o: In function main': C:\Users\Adrian\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6\cores\arduino/main.cpp:43: undefined reference to setup'
collect2.exe: error: ld returned 1 exit status

please help me solve this problem asap because my anniversary passed 11 days ago and i have to give this gift to her by the end of the month at the latest. i appreciate the help.

every sketch must have setup() and loop() functions. don't delete them even if they empty

oh my god i'm so embarrassed. i saw this solution and i checked my code and thought i had them both there but i just did a re check and just saw apparently i didn't. thank you so much.
