I Saved C# Project form as a new name, now project is broken. How to fix it?

Question

I have a C# project in Visual Studio Community 2022 with a single form for the interface. I made some changes to the form and wanted to save it as a different name so I could preserve the previous design. Now I cannot see the form in the designer, but instead a windows with the message ...

"To prevent possible data loss before loading the designer, the following errors must be resolved: "

Can anyone explain how to resolve this?

UPDATE: I was able to get back to normal by renaming the filename extensions of the new .cs and .resx files. VS should be better than this.
