4.1.1 and 4.2.0 Slow start and sudden crash issues

I am cross posting an issue that I already reported on Gihub without any answers. Maybe someone here will pay attention to it:

4.1.1 Issue: Slow start. Docker needs almost 15 minutes to start after a reboot of the PC. If in that time, the Docker Hyper-V VM is manually restarted, Docker starts immediately.
4.2.0 Issue: The one from above plus sudden crash. I just notice that Docker is not running anymore. After a reboot it works ok (God knows until when).
