Windows 10 Ethernet adapter disappeared

My Windows10 PC has no ethernet network connection since yesterday. The port is part of the ASUS X570 motherboard. In 'View Hardware and Connection Properties':

• Ethernet: Status is Not Present, Connectivity is Disconnected.
• vEthernet Status is Operational and Connectivity is Disconnected.

Ethernet adapter isn't present in Device Manager.

Steps:

• Reset router/modem
• Tried different ethernet ports on the router
• Changed the ethernet cable
• Network Troubleshooter comes up with no results.
• Tried reinitializing all network states as suggested below.
• Windows Network Reset
• LAN Controller in BIOS is on
• Delete vEthernet Adapter in Device Manager
• Green ethernet port LED is on when cable is plugged in, orange LED is flashing
• Reinstall drivers

The same router is connecting successfully to an RPi4 via ethernet, and wifi works for my MacOS laptop and Android phone.

I'm wondering if this is a firewall or network setup issue. If so, what are steps I could take to troubleshoot? I had previously messed around quite a bit with my ports and firewall settings.

Try completely reinitialising all network states.

Run the following commands in an elevated (run as Adminstrator) cmd shell:

• Reset WINSOCK entries to installation defaults (reboot required):

  netsh winsock reset catalog

• Reset TCP/IP stack to installation defaults:

  netsh int ip reset reset.log

• Reset Firewall to installation defaults:

  netsh advfirewall reset

• Flush DNS resolver cache:

  ipconfig /flushdns

• Renew DNS client registration and refresh DHCP leases:

  ipconfig /registerdns

• Flush routing table (reboot required):

  route /f
