Network Bridge from the Network Connections UI is not working on build 22000.100. It's broken as shown in bridging adapters for ethernet to wifi bridge.
For Thunderbolt adapters, Network Bridge WAS working on 22000.71, now not working at all on 22000.100 - once bridge connections is selected for two thunderbolt adapters the UI freezes, COM surrogate can be seen in the task manager as well as an additional explorer process, both processes are frozen, the Network Connections UI is frozen, only way to free up the UI is to kill both tasks.
Please fix. The ability to bridge two thunderbolt adapters is a boon to thunderbolt networking, much more difficult without it.
