Rename "fill_nodes" file to "old_fill_nodes". You can find it in the .metagate folder.
After that - restart the app. Not enough to click "X" and icon again to restart MetaHashGate. You should click "Quit" in the tray(this line will appear after click of the right button).
If previous ways didn't help, you need to reinstall the app. Download latest version of the MetaHashGate from GitHub - https://github.com/metahashorg/metagate/releases/
