6571 encounter error -1074102162 during initial

Hi ,

     In my test case, I use a SMU and 6571.  We will occasionally have error from SMU and then our test sequence will skip the close session step of 6571.  When we try to run the test sequence again, we will encounter this error -1074102162 in 6571 initial every time.   

     And when this error happen ,  windows will turn to blue screen 10 sec after error happen. 

only power down first and power on again can fix this issue. 

     Not sure what happen.  

     We're using digial pattern driver 19.0.1
