Could you check this again with the latest version (clone the repo and checkout dev branch)? Some Internal compiler errors were fixed since the version in vcpkg.

[dancazarin]

In the current version the code you provided doesn't cause internal compiler error in Visual Studio. The issue can be closed as completed after confirmation from you.

Yep, thank you for the support :)
