RibbonWindow C# Invalid Markup (xaml designer not loading)

I have a project with syncfusion WPF (.net 7) and everything is working fine except the designer for the RibbonWindow. 

I get the following error : 

XDG0008 The name "RibbonWindow" does not exists in the namespace "http://schemas.syncfusion.com/wpf"

Whatever I do it still pops up.

What do we need to do in order to overcome that error?

I followed this : https://help.syncfusion.com/wpf/ribbon/gettingstarted

I have the same thing than that and still the error comes out

Hi Eric,

We have checked on your query but the issue is not replicating from our end. Please refer to the sample and video for your reference. If you are still able to see the issue,

Could you please share the following details

1. Version you are using for VisualStudio and Syncfusion.

2. Video replicating the issue.
