IWR6843AOPEVM: Connect but failed GUI application

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: UNIFLASH, IWR6843

Hi,

I got two IWR6843 AOP Plug-in module today. I used uniflash to program the "aop_pplcount_lab_68xx.bin" of lab20 to both module. And use the "GUI_A_base_no_logic\main_pplcount_viz.exe" to execute the people count evaluation. I did install the "CP210xVCPInstaller_x64.exe" SICP2105 UART driver, set the UART port with Enhanced COM, set DATA port with Standard COM and reboot my PC before evaluation above. The result is I successfully execute "main_pplcount_viz.exe" people count on my first module but failed on the second one. The error message in console as following:  Please help how to fix it on my second module, or the module is actually as NG module?
