Issues compiling older ASP.NET Webforms app in .NET 4.8.1 in Visual Studio 2022

I originally had an old site building in Visual Studio 2019, but since getting a new laptop and going to Visual Studio 2022, it won't build any longer and I get the below errors shown in the screenshot.

It was originally written in .NET 3.5 using ASP.NET Webforms. Then I switched to .NET 4.8.1 and it ran in Visual Studio 2019. Now it won't run or build in VS 2022. It only errors on one of the projects it seems - a project library.

Make sure you have a reference to Microsoft.CSharp.

If not, then right click on references, and add it:
