Did you try following the advice I provided already in this thread?:

OK, let's try some drastic action. Be aware this is somewhat advanced and will remove any boards you have installed via Boards Manager:
- Click the link on the line following File > Preferences > More preferences can be edited directly in the file. This will open the /Users/brunoloverius/Library/Arduino15 folder.
- Delete all files and folders under the Arduino15 folder except for preferences.txt. Please be very careful when deleting things from your computer. When in doubt, back up!
- Restart the Arduino IDE
Verify that you can now use your board before reinstalling any packages via Boards Manager.
