I've improved the ability to troubleshoot issues like this in the latest release (v2.3.0). Do you mind trying that out and exporting a log file for me to check out?

You would just have to:

1. Install v2.3.0
2. Give the app root permissions
3. Go to the "Troubleshooting" screen in the overflow menu in the top right
4. Click the button at the bottom to export logs (a screenshot of the troubleshooting page would also be nice)
