Visual Studio 2022 with WPF using WPF UI bug

This issue has been moved from a ticket on Developer Community.

[severity:It's more difficult to complete my work] I have a project using WPF and Visual Basic and i installed the WPF UI library, i was working normally but today when i started my project all the controls visualization was wrong, the controls of the wpf ui library still appear and seems all normal but in the xaml visualization page they appear exacly as the default controls from the standard WPF, i tried everything, installed the library again, cleaned and recompiled the project but still nothing changed. I Tried updating Visual Studio and WPF UI but the problem stayed. I even created a new project to see if my project was corrupted or something but it still does not work correctly, the new project was having the same issue, so i think the problem is from visual studio. I need this to complete my work....
