PyInstaller: UnicodeDecodeError: 'utf-8' codec can't decode byte 0x87 in position 112: invalid start byte

Question

I was trying to convert my project to the exe with PyInstaller, I tried the solution on this link with two options: Error when using pyinstaller: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff

Also tried this solution, changed all 'utf-8' encoding to the 'cp1252': UnicodeDecodeError: 'utf-8' codec can't decode byte 0x96 in position 35: invalid start byte

But it could not solve my issue:

An error occurred while packaging

@NicholasObert it's 7779 lines are you sure about that? if u want i can upload in 5 min to external link on gdrive — Fatih Tüz
mhh i guess that's not a great idea. Try different versions of pyinstaller, as @Sajad.sni suggested — Nicholas Obert
At least its free and quick!!. As I can see in my python package manager there is an update for pyinstaller to version 4.0. maybe downgrade to previous versions fix the problem since there is not enough clue to figure it out. @NicholasObert — Sajad.sni

It's interesting but, upgrading auto-py-to-exe solved my problem. I tried almost everything, but this basic solution was the one that made issue i guess...
