title: Visual Studio 2019 - C# Windows Forms Designer- Not able to add items from the toolbox
body: <p>The issue is explained quite simple.. everytime when I try to add an item from the toolbox there is the error message: Object reference not set to an instance of an object.</p>
  <p>I choose an item.. e.g. a button and drag and drop it to the form.. after releasing the button the error message with the object reference appears.. everytime..</p>
  <p>After the message the item is visible in the form. I would like to fix this issue.
  I am using the community version with .NET Framework 4.7.2</p>
