z490 Aorus Master - Lost LAN device (225v)

[FranzOmz]

OS: Windows 11
MB: Z490 Aorus Master
CPU: 10900k​
Ethernet: i225 (probably. Don't know how to check)

After some reboot I lost my LAN connection. Only WIFI is working.
I found that there is no LAN device anymore in device manager.

I tried:
1. Update ALL drivers from the Gigabyte official website
2. Update intel drivers from intel website using manual installation and ther automatic launcher. In case of the automatic launcher it says: No intel LAN device found
3. Tried to update the BIOS to the latest version
4. Tried to flush dns, reset network settings in windows, etc...
5. Have latest windows updates
6. Did a windows reset. Not a hard reset, kept my files, but deleted all the apps.

When I plug the ethernet cable in, I see the light blinking on the ethernet port. But nothing happens.

I asked help from a gigabyte support, but after 4 weeks no response
Don't know what to do and what else to try. I would really appreciate any advice or ideas.

I found a tip that Gigabyte can share an NVM firmware via support channel. And it should help me to get the LAN card back online.
Is is a possible solution?

Hey, sorry for delay. I'm going to perform the clean windows install during the weekend.

It's hard to do during the Monday-Friday, since it is a working PC
