Android Studio shows C++ file icon on every file

Question

After updating Android Studio to version 4.1 every file icon in the project is shown as a C++ icon. Is there any way to repair this? This is how it looks:

You can see every file, no matter what extension, has icon. I created new projects and checked the old ones but the effect is the same everywhere.

In my case, the error disappeared after updating Android Studio to version 2020.3.1.

Answer 1

What i normally do is clear Android Studio's cache, forcing it to rebuild icons.

Go to File -> Invalidate Caches / Restart.
