hi,

I think you are using Visual Studio 16.9.
It's a know issue and our devs have found a solution.
I've written this post about it and how to fix it.

You have two line to modify in the framework, this update will be included in the next release.

Let me know if this doesn't fix the issue.

Cheers,
Manuel

Thank you for your advice. The build was successful !!
