I am trying to build a project using Visual Studio 2019 and C# but it fails.
CSC : error SI0001: Object reference not set to an instance of an object.
There is not any specific info and I do not know where to look at. I will appreciate some help. PS: I did not change anything in this project and it works for my colleague.
thank you in advance
