Hey,
if I double clicking on a "DataBand" in the designer I get the following error, any ideas?

I am using:
- Windows 10 (latest release)
- Visual Studio 2019 (latest release)
- .NET CORE 3.1 (C#)(WinForms) (latest release)
- Stimulsoft.Reports.Engine (latest release) as NuGet Package
- Stimulsoft.Reports.Net (latest release) as NuGet Package
- Stimulsoft.Dashboards.Win (latest release) as NuGet Package
