ActiveX error from a vi called by TS

Hi,

 

I can’t find an answer about this error

-18001; An error occurred accessing the LabVIEW ActiveX automation server.

I’m using labview 2021 and TestStand 2021 I have a huge sequence and it’s always worked fine. Now I’m receiving this kind of error every time I call a vi that uses a self-made library (except when I enable the Highlight Execution). I don’t understand way only now, since I have used that library also during the past years and nothing has never happened.

 

The only help I have found only is here:

But it isn’t the same error and I don’t understand the difference in using a LabView Run-Time Engine and the LabView development System.

Is there someone who has already receive an error like that or know how to debug it?

 

Best Regards,

Zuc
