Hi @Shyam Pilla,
I tried to access the link that you shared above but it seems that there were some limits, so that I failed to access that link.
From the screenshot that you shared before, it seems that this is a third-party extension? I also tried to search in Visual Studio Marketplace but failed to find it. I guess it can be only downloaded from its official website?
Besides, I notice that you mentioned
It successfully opens in few workstations.
Do you mean it works correctly on other machines with the same version of VS 2019 Professional?
If so, I suggest you firstly try to reinstall this extension. Make sure that the versions(VS 2019 Professional version and the extension version) are correct.
You may need to double confirm the extension installation/usage guidance. Make sure that the required components have been installed.
As, even the icon of this explorer doesn't show correctly in VS, I doubt if it is compatible with this version of VS 2019 Professional. If its official website provides the detailed installation requirements description, it will be easy to confirm and narrow down this issue.
Regards,
Tianyu
