Same problem here with: Win 10 VS Pro 2022 17.1.6

Additionally: CommunityToolkit.mvvm (7.1.2) Microsoft.aspnetcore.signalr.client (6.0.4)

Even a completely new, empty WPF window will not show in the designer. All usual actions like clean recompiling, removing all temporary and generated files, restarting the VS, etc. didn't help to address the problem.
