I have a project in VS2022 targeting .NET 6.0 and using the UI.for.WinForms.AllControls.Net60 NuGet package. On installation of the package all controls appear in the Toolbox as expected. Upon restarting Visual Studio, all of the controls have disappeared. Attempting to re-add them manually from Choose Toolbox Items and browsing to the package DLLs results in errors as below for each DLL.
Do you have any suggestions as to why the controls won't persist in VS?
We've tried uninstalling and re-installing VS so as to start with a fresh install but the same issue occurs.
