Question Ethernet adapter no longer working after restart

My hardwired ethernet connection is no longer working after turning on the computer after a week away. I have tested the ethernet cable on another computer and it is working, the router is working, and I am now using the computer with USB wireless adapter. I'd like to troubleshoot the ethernet connection though. I am on Windows 10, Gigabyte Aorus Z590 Elite MOBO.

In device manager, the Gigabyte Realtek network adapter was not showing. It showed under hidden devices, but was listed as disconnected (Code 45).

I uninstalled the Realtek driver from device manager, then reinstalled with drivers from the motherboard manufacturer (as admin, trying all versions, rebooting after install). The realtek adapter has never showed up again in device manager after resinstalling the drivers, which is concerning.

Other things I have tried:
  • Windows troublshooting > Reset network connection
  • Tested ethernet cable with a laptop > works
  • Rebooted in safe mode > ethernet still doesn't work
  • Command prompt >
    • netsh winsock reset catalog
      netsh int ipv4 reset reset.log
      netsh int ipv6 reset reset.log
  • BIOS > checked status, LAN adapter is enabled

I am concerned the adapter itself on the mobo may have just fried, but I'd like to explore the other options before giving up on it. Any thoughts on what to troubleshoot next?

Run "ipconfig /all" (without quotes) via the Command Prompt.

Use copy and paste to post the results.

Does the network adapter appear if you use Powershell's Get-NetAdapter and Get-NetAdapterHardwareInfo cmdlets?

Just use the basic "Get-" cmdlets. Post the results.

Do be aware that your network name may be revealed - just redact the network name with "REDACTED".

Get-NetAdapterHardwareInfo :
No response at all, just moves to the next input line in powershell

Let me know if there are other specific Get- commands I should try, it looks like there are quite a few but many do not return a response
