Trying to program in c++, E1696 errors, basic Unreal architecture not linking properly, redownloaded everything, files missing or replaced

The title says it. I was following the programming quick start guide where you make a floating cube in C++. That worked, and then I experimented changing the referenced cube shape with toruses and other shapes in the content drawer folder it referenced, and that was updating slowly and inconsistently but it was updating. I might have changed some preferences or settings in visual studio but it caused it to have a ton of errors I assumed must have been because the fundamental components weren’t being referenced correctly anymore, and it wasn’t recognizing the headers a lot of files were including without my involvement, and basic classes. I couldn’t figure it out so I uninstalled and redownloaded the engine and visual studio 2026 (couldn’t figure out the installation for 2022 and assumed there wouldn’t be too much difference). Now I’m seeing the following issues on ScriptGenerator.cs and UnrealEngine.csproj.props from what I can tell. Everything is a mess and I’m completely new to incorporating libraries and API’s effectively, especially of this size, so I have no idea what I’m doing frankly.
