android studio makes corrupted Colors.xml, then unknown errors occur [duplicate]

Answer 1

This is a known bug which reported by many developers and I've faced that once.

The only fix is to reinstall the Android Studio or downloading the new version of the IDE but, don't import the old config when you reinstall or updating it.

To be clear, changing File-Encoding in settings to UTF-8 or System Default doesn't work either.

Answer 2

You don't need to reinstall Android Studio: close it, and delete the folder .AndroidStudioX.Y (X and Y depends on your Android studio version) in the user folder.

The answer is old, but I have the same problem today with Android Studio 3.3.2. I give my answer with the hope it can help other developers. In a random way, Android studio cannot open some files. In the first instance, I thought that the files were corrupted. After opening the same file with an external editor I realized that is not true.

In the above example, the .iml file cannot be read by Android Studio. I open the same file with Notepad++ and I luckily saw that file was good.
