Building VXGI2-4.21 issues

Hello there,

For some reason when I building UE4 VXGI2 4.21 project, the entire build gets stuck at this stage(picture attached below).
It got stuck there for 20 hours now!

Somehow I managed to build both previous builds 4.18 VXGI and 4.19 VXGI without those kinds of issues.

Did anyone have a similar problem?

Suppose I am missing some additional features for Visual Studio 2017 which I don’t know about it.

Please, I need some help here.

Thank you in advance

Elmo
