Devices/Android versions reproduced on: Samsung A53 - Android 14

When trying to filter the scan results by an exposed service UUID, the library throws a NullPointerException in some devices. Filtering just by the deviceName works as expected.

This bug does not occur in all devices. I've also tested it on a TCL 30 with Android 12 and the filtering works as expected.

 val filters = listOf(
    ScanFilter(serviceUuid = UUID.fromString("000000A0-0000-1000-8000-0042486F7574")),
    ScanFilter(deviceName = "Device Name"),
)

Caught a RuntimeException from the binder stub implementation.
