I tried it like this, still the same error throws. Also I tried removing a few characters from the file and repackaging without adding anything, the error throws again.
It is weird, since I tried to repackage without any changes and the game loads in without any issues.
Is there an issue in my repackager? Feel free to check the code in my first post.
I personally think that it is either a unicode or signature error, I can't tell though...
