No Internet Access, SimpleDNS crash, service not starting.

I'm frequently losing network access with error: No Internet Access - your device is connected and can access other devices on your local network, but you may not be able to reach the internet.

When I open SimpleDNS I find the resolvers page empty and after a few seconds SimpleDNS becomes unresponsive and crashes. Other times I have found the DNSCrypt service fails to start when Windows starts. I use Malwarebytes Firewall Control and don't know if the issues I'm experiencing are linked.

Can anybody help with this?
