You should update Visual Studio to version 17.2.0 Preview 5 in order to use the latest Telerik UI for .NET MAUI (Preview) 0.8.0 as it is built against .NET MAUI Release Candidate 2.
You can check the release notes of Telerik UI for .NET MAUI Preview 0.8.0 at the following link:
Virtual Classroom, the free self-paced technical training that gets you up to speed with Telerik and Kendo UI products quickly just got a fresh new look + new and improved content including a brand new Blazor course! Check it out at https://learn.telerik.com/.
If you used the nuget version, simply update.
Otherwise download 0.8.

I tried it with VS 2022 17.2 Preview 5
Give it a try, otherwise go back to 0.7.
