Android Studio - AAPT: error: file failed to compile with PNG images

Question

I was working on Ubuntu linux and recently i pulled my project and started working on Win10.

From now on i cannot Build/Run my app. There must be a problem with those PNG files in the resources folder.

That is the Error output while trying to build the app :

I don't know what is causing it. I cleaned cache, delete and pull project again. Also i couldn't find a solution online.

Update Found out that Android Studio on Linux(Ubuntu) works just fine and as a matter of fact this error occurs only on Windows' Android Studio..

If some files have been encrypted, AAPT may not work properly. Please check whether the files related to the compilation error are encrypted. In your case, these are PNG files.
