can't seem to fix "Error Creating Control"

[Rich]

My issue is the gauge control won't render in design mode:

Error Creating Control - GaugeuserCountFailed to create designer 'Telerik.Web.UI.RadRadialGauge, Telerik.Web.UI, Version=2020.2.617.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4'

 

I've got a reference in the project page to the .40  .dll   version..

Project builds & runs fine, just cannot get this to work!..

This is VS.NET 2017 on Windows 10

I've tried deleting files in:

%AppData%\Local\Microsoft\VisualStudio\16.0_1695dc1b\ProjectAssemblies, Cleaning & REbuilding the solution..

Help!

I submitted a ticket, so I guess ignore this?

I didn;t see an option to delete..

ok, it is resolved: though I'm not 100% what I did...
