I found a small fix that will make you play without losing your progress.

Many programs like Docker, Android Studio, and Yakuza, have issues with
special characters like:

- accents
- cedillas
- etc

Certain code compilers can't read such characters, but that happens mostly in windows, you don't usually have issues like those in Linux distributions. What do i mean by that? Your windows user account probably has a special character in it.

Here is an example. You can't change that. So what you should now do is:

In your windows, you should create a family user account (It will create a sub user on your PC, and it will transfer all your installed programs to it), make sure you create an user with no special characters! Once created, switch your new family windows user.

I created a user called "simas", instead of Júlio (my main windows acc)



Here it is, my new user. Everytime you want to play Yakuza, switch your user, and play it. Don't try to change your administrator folder, it will create conflitcs or even corrupt your files.
I hope i have solved your problem. Enjoy Yakuza.
