Android Studio automatically generate several files and folders to store configurations, cache, etc. Above issue happens when Android Studio messes up one or more of these files and folders. Solution is to delete them. So when the previously saved files are no longer available, Android Studio creates those configurations back again.

This won't affect any of your projects or the changes which you have made to Android Studio (Settings, themes, Keymaps, etc.)

All the attributes are now shown as before.

Suggestions are working as well.
