Answer 1

Thanks to the Answer of Asim, I found deleting folder caches fixed the problem for my case (all gradle files in Android Studio show contents that have nothing to do with the actual contents of these files):

C:\Users\my_user_name\.AndroidStudio3.3\system\caches

This is still happening with Android Studio 4.0, so I have to delete the following folder to fix this problem:

   C:\Users\my_user_name\.AndroidStudio4.0\system\caches
