Additional Information:

The Background Discovery Broker is a relatively new service, introduced in Windows 10 version 1903, and its purpose is to make it easier for apps to find and connect to devices, such as Bluetooth devices, printers, and scanners.

The DevQueryBroker service works by running a background task that periodically scans for devices. When it finds a new device, it sends a notification to all apps that have registered for device discovery events. This allows apps to quickly discover new devices without having to continuously scan for them themselves.

If you are having problems with an app that is trying to discover a device, you can try restarting the DevQueryBroker service.
