Moreover, using this particular rule in "Local+DNS+DHCP(svchost)" won't do anything at all. It will still prompt for error.

You can easily reproduce this error by disabling the DNS client in services

As you could notice there is a
”WindowsFirewall:” substring in the blocked event description.
WxFC shows all the blocked notifications regardless of the origin, including WindowsFirewall events as well.
So the block is made by WindowsFirewall.
When you have 2+ firewalls installed/operable concurrently, the firewalls work in sequence.
So in order to enable an activity, the activity must be enabled in all the firewalls.
If WindowsFirewall blocks the activity, the activity will be finally blocked in spite of WxFC enabling settings.
Please use a WindowsFirewall related panel to enable the activity.
WindowsFirewall may insert hidden blocking rules to reflect the policy – Disable everything that is not evidently enabled. So you may want to change the policy or add an evidently enabling rule into WindowsFirewall.

The problem is, the Windows firewall is not turn on, nothing is running.

WxFC marks any none-WxFC (third party) blocking as WindowsFirewall related.
So it may be any third party, an Antivirus embedded firewall or so.
However “WSH default outbound block” is a rule generated by WindowsFirewall typically.
By default the rule is injected by WindowsFirewall.
We would recommend you using the “WindowsFirewall with Advanced Security” panel to restore WindowsFirewall's defaults via Action/Restore Default Policy.
Anyway the rule name points to WindowsFirewall as the blocking entity.
Actually the screenshot confirms that WindowsFirewall is switched off, but it’s only a control panel. All the underlying services most probably are running and may have an inconsistency.
Please try to Restore Default Policy and keep us up to date.

restore firewall to default seems fix the issue. Anyhow, the firewall is NOT turn on at any given time. I don't understand why that make a difference.

Just a hypothesis.
WindowsFirewall (WF) consists of 2 parts: the control panel (that is typically perceived as self sufficient WindowsFirewall) and the related WF service, that is actually implements the security policy.
The service may accumulate an “entropy” and have inconsistency.
When you switch WF off via the panel, the service is still up and running.
If a filtering rule was “inserted” into the service by mistake, bug or an accident, the rule is persistent and does not depend on the state you can see in the panel.

One thing was confirmed and is clear for sure. There was a “WSH default outbound” rule generated by WF. The rule got stuck in the service and the rule presence did not depend on the WF visible (in the panel) state. After all the rules were defaulted the rule was removed as expected.
