Environment
Using Windows 10 Version 22H2 (19045.3930)
Microsoft Visual Studio Enterprise 2022 (64-bit) - LTSC 17.6 - Version 17.6.11
Repaired my Visual Studio 2022 installation, no change
.NET version
.NET6-Windows10.0.19041
Did this work in a previous version of Visual Studio and/or previous .NET release?
.NET Framework 4.7.2
Issue description
We have recently upgrade all out projects .NET 6. Many of our software developers experience that they are unable to use the WinForms designer in VS on the .NET 6 projects. For some users it does work.
We followed the troubleshooting guide, but no luck.
We found the out-of-process documentation and enabled both the out of process designers 
I have managed to reproduce my problems in a sample project, so i will report this behaviour.
I set the Windows Forms log verbosity to detailed.
When creating a new solution in VS 2022, creating a Windows Forms net6.0-windows project with the default form, the designer can load, showing the default empty form.
This produces below output (in diagnostics section) and properly shows the DesignToolsServer.exe as a child process of the Visual Studio instance.
To break this, all i need to do is add a PackageReference to one of the DevExpress WPF packages, which in our production code might happen using transitive dependencies.
<ItemGroup>
<PackageReference Include="DevExpress.Wpf.Core" Version="22.2.4" />
</ItemGroup>
After doing this, without even using any controls, the DesignToolServer is failing to load, producing this below log file.
If have also tested using the DevExpress.Win.Design package, when adding a reference to this the design still loads.
Sometimes, but not always, i am seeing this exception when closing the hanging designer

Steps to reproduce
Create new solution with NET 6 Windows Forms project
Add PackageReference to DevExpress.Wpf.Core version 22.2.4
Open designer
