Answer 2

Ran into the same issue. Seems to be something specifically related to Android Studio 3.2. My solution on Windows was to delete everything withing the cache/ folder in the .AndroidStudio3.2/ folder.

This problem happen for Android studio Cache & History.

Firstly In android studio go File -> Close Project and Exit Android Studio.

Then Delete below 2 Folders:

• C:\Users\user-name.AndroidStudio3.X\system\caches
• C:\Users\user-name.AndroidStudio3.X\config\terminal\history (optional)

Open the Android Studio and Enjoy!
