I think I have misconfigured VS 2022 (out of ignorance) but I can't build my project due to dozens of errors that I have been unable to resolve. I ran into this issue with the project I was working on, and to try to figure out if the work I had done had caused the problem I made a new C++ Unreal project, but the same errors were present in that project before and after I added new C++ elements to the project from inside Unreal.
Here are the errors I'm seeing:

I have tried updating VS 2022 to the Insiders version following a suggestion from a another user on this site (in response to a similar issue) and have used NuGet Package Manager to make sure all of my packages were the most recent versions.
