Android Studio3.5 suddenly cannot resolve symbols

Question

Android Studio3.5.3 suddenly cannot resolve symbol xxxx error occurs. and even cannot load some java file, showing wrong characters with UTF-8 encoding.

Well I searched online and tried the Invalid & Restart methods, but that did not work at all.

Someone please help me out. Thanks.

As @MarkusKauppinen provided post: Android Studio shows wrong file contents

This is the key: Delete the caches folder: C:\Users\my_user_name\.AndroidStudio3.5\system\caches
