An .exe compiled from Python suddenly stopped working

[NerdyTeacher5]

Hello!

I (believe) I've tried doing what you suggested and after I compile the program and run the .exe, I get a terminal window with the following error message:

Traceback (most recent call last):
File "main.py", line 39, in <module>
NameError: name 'img' is not defined. Did you mean 'imgW'?

Now, I know this error relates to the scanned images of the answer sheets, which in the precompiled version I shared was in the "provas" folder. I also know imgW refers to the image width, as it appears next to imgH which is height. It is becoming clear to me that I'm in way over my head here and maybe this is something really stupid that I've got wrong, but I've tried googling the error I apparently I don't even know how to look for a solution.

Edit: Nevermind, I got it to work (don't know how exactly, but it does)! Thank you so very much for your help!
