Hello,
when starting (debugging) our Application with Visual Studio 2019 with AnyCPU we receive a System.NullReferenceException at NationalInstruments.Internal.SlcpHelper.d(). See Error_01.png and Error_02.png.
When we set "prefer 32-bit" in the project-settings (see App-Settings.png) it start without Exception.
.NET-Framework 4.7.2 and 4.8
Where is our Error?
Do you need more Informations?
