VBA SelectElement function not updating screen

Hi everyone,

As sumed up in the title I have problems by using the "SelectElement" (even "SelectElement2" and "SelectElement3") function in VBA macro. Currently I am using an external app created with VisualStudio running outside of CATIA. Everything works fine except one thing, when I start the macro with the "SelectElement" function the screen in CATIA doesn't update, it lets me select but I can't see what I am doing because it appears as freezed. Does someone know what could be the problem?

Currently I am using 2021x Hotfix 4.3 version of 3DEXPERIENCE PLATFORM on Cloud, it worked all fine with the previous version FD03, 2021x Hotfix 3.x 

Let me know if you need further informations

Thanks in advance for helping!
