MacBook Pro ethernet adapter not working after 26.2 update

Using my MacBook Pro 14-inch, Nov 2024, M4 to coordinate frequencies on Shure's Wireless Workbench 7.8

Was working beautifully before I updated to 26.2 and now I can't get any ethernet adapter to work. I've tried 3 different USB-c and thunderbolt ethernet adapters.

I see the lights blinking, it's talking to the switch I'm plugged into for local network, but no devices are showing up in the Workbench software.

Never had any issue before the update. Have not changed any IP or network settings. Only thing to change is the OS.

I use a 10 dot local network not automatic IP. Subnet is all the same. (again, I have not changed any of these settings)

Normally I see 27 devices on this local network when I plug in. and I get 0 now.

MacBook Pro 14″
