Hi @ChendongSun , I can reproduce this issue. Yes ,it indeed the same one with #614
In your steps, it happend after updating the drivers via the installer, actually even only with your first step, and plus restart blnsvc service, it also can be reproduced.
The trigger condition is:

1. install blnsvc by the installer.
2. restart blnsvc in service manager.
