Navigate through the source code or xaml conceptor without error.

Hello to all,
This project is inspiring and includes some great design ideas for a WPF application.
However, being able to open it in visual studio without errors appearing is a nightmare. There is obviously not enough information or a simple tutorial that works to get started.
For my case, and surely for many people. Opening the solution with the latest version of vs2022 and the necessary frameworks 4.5.2 4.7.2 .netcore5 .netcore6 and using it correctly is impossible.
The demo runs without problem but impossible to open some pages with the xaml designer (like the "fields" page) and errors come out everywhere (members not accessible / unset values of setter methods)... a real nightmare . Look at a modernUI application from Lepo on github. it works the first time.
I propose this conversation. That everyone can open the source project without problems.
