IWR6843AOP: About the vital sign example on IWR6843AOP

Hello,

We're trying to run the vital sign example in mmwave_industrial_toolbox_4_4_1.
And, we're facing the error that the continuous two operation doesn't work correctly due to MSS Exception.
We have two questions.

1.Is there any CLI commands that reset IWR6843AOP?

2.Could you confirm the following log and tell us the reason of the error?

Following is the log that IWR6843AOP output when the first operation after power-up.
