cx_Freeze executable fail, not sure how to integrate a fix?

I finally got a piece of code I wrote into what seems to be a somewhat executable style. I ran into an error on execution:

 Fatal Python error: initfsencoding: unable to load the file system codec
 ImportError: invalid flags 1540019631 in 'encodings'

 Current thread 0x00007fff77a44000 (most recent call first):
 Abort trap: 6

I've tried using cx_Freeze to convert my script to an executable. The cx_Freeze seemed to work, and I got a file in the correct folder.

But, upon trying to execute it I got the above error. I found a fix here:

https://github.com/msys2/MINGW-packages/commit/4c18633ba2331d980f00aff075f17135399c43c5#diff-ae075c6e3ef8ca1f65e55241d3683992

and found the

 freezer.py

file. But, do I add the code in the code directly to this file at the very beginning or am I seeking specific sequences to insert it? When I put it at the beginning of the freezer.py file, I get a series of errors related to the freezer.py file that now prevent converting to executable.

I appreciate any help you all could offer, sorry for the really lame question!

Basically I inserted

right after the import cx_Freeze in the freezer.py

I expected successful conversion and an executable, but I got the following error:

After trying to integrate the fix, I got the following error BEFORE any conversion had occurred:

Traceback (most recent call last):

Not sure how to properly integrate the fix :(
