TabPage Background Causing Winforms Designer to crash

Question

Hello,

We have been having an issue with the .Net Framework (v4.8) Winforms Designer crashing after build and running of the application.

I have tracked it down to when the tabpage control has an background image applied.

Here is a sample of the code:

tabpage1.BackgroundImage = global::GloablResources.Properties.Resources.someImage;

The tab control is a custom control, but we do not override any OnPaint events.

The resx files are centralized to another DLL.

Here is the error presented to by the designer.
