There was a problem with the WPF

I was presented with a problem, in the visual studio 2019 in Windows Presentation Foundation (WPF) that does not allow me to observe the design and sometimes the visual when loading my projects closes, but that happens when I put the WPF, I thank you in advance for your support

@marco1408 maybe try deleting the .vs directory in the solution folder.
