I use in XAML file open browser activity set as chrome but it was run in the “chromium” why?

And throws an error too ?

Any update on the error “Cannot communicate with Internet Explorer browser” triggered by Open Browser activity? With Chrome it works, but not with IE.

I’m using:
IE11: v 11.407.17134.0,update versions: 11.0.95 (KB4466536)
Win 10 Enterprise, v 10.0.17134 build 17134
UiPath Studio Community 2018.4.1, Win 10 64bit, .NET framework 4.7.2

Thanks
