Hi team,

**Description**  
I’m trying to start meeting using StartParam4WithoutLogin. When I hardcode the parameters for RestAPIUserStartParam and run my program, the application runs without any issues.

When I try to start the application by passing these parameters using a batch file or by starting it through command line, I get a pop up below popup:

Sometimes(1 out of 5) the meeting starts as expected but most of the times I get the above popup and meeting does not start.

**Which Windows Meeting SDK version?**  
**zoom-sdk-windows-5.11.1.6653**

Please guide me to fix the issue.

Thank you!
