There are currently issues on macOS devices with T2 chips and OWL. I was able to reproduce your issue on my MacBook Pro 2019, 15". We will look into it and see if we can deliver a fix for this next week.

Hi, After some investigation we discovered that this is a known issue depending on Bluetooth Low Energy (BLE) messages. Our current implementation is network only and to discover your devices AirDrop normally sends BLE advertisements at first. Those advertisements inform all surrounding devices that an AirDrop sender is looking for devices. After they have received this advertisement they will activate their AWDL interface and set up a peer-to-peer connection to your Mac.

In fact, you can solve this issue by opening AirDrop in Finder. Then you Mac will start sending the BLE advertisements. Then OpenDrop will also find all devices:
