My Android Studio has some text or font error or language error because of that I can't understand and use its controls.

Hello guys. I am really in such a doomed, I don't know what has happened to my Android Studio. The first time I installed it, it was working pretty well except that it has some gradle error with the 32-bit version I am using. So I reinstalled it, and this what happened next: 

You know, it should not happened. I perfectly did download it here: https://developer.android.com/studio/index.html.

(I recently installed the old version, hoping that it would work fine but it didn't).

After seeing that malfunction in my Android Studio, I did everything to solve it:

-Uninstalled it completely

-Restart the computer

-Reinstall

-Tried the old version (to see if it will make a difference)

-I even run the antivirus, downloaded Roboto, Droid Serif/Sans, and create a new user account on my laptop then installed it there the (32 bit version).

I don't know what is happening, I need to finish my mobile app in January and I can't use Android Studio! Please help me. Thank you very much.
