When the previous device is disconnected and another device is connected, the connection is successful, but an error is reported discoverServices

The first connection is successful, discoverServices can be successful

PeripheralProxy.cbPeripheral.delegate is nil

       ` let UUIDs = [peripheral.identifier].compactMap{ $0 }
        guard let per = retrievePeripherals(withUUIDs: UUIDs).first else { return }
        self?.connectPeripheral = per`

I solved this problem by reacquiring the device list and I found that each time the scan was completed, the PeripheralProxy was released
