According to the API docs for getDefaultAdapter

This method was deprecated in API level 31.
this method will continue to work, but developers are strongly encouraged to migrate to using BluetoothManager#getAdapter(), since that approach enables support
for Context#createAttributionContext.

They say it will continue to work but it looks like it doesn't in this case.

You should remove the Try / Catch block and post the full error message.

You need to declare the permission with AddPermission(android.permission.BLUETOOTH_CONNECT) in the manifest editor and request it at runtime with rp.CheckAndRequest("android.permission.BLUETOOTH_CONNECT")
