I have the same issue and tryed the solution with building via VS Code. I got these warnings and error message:

Ok I have no idea if this was the right way, but I first generated visual studio project files
and now I have additional errors when building:
in another forum thread I found a suggestion to install SDK NET 7.0 and NET 6.0 (I don’t even know what that’s for).
I tried building again, same errors.
1 Day Later:
I gave up on this approach. But what worked for me was creating a blank 5.4.2 Project and migrating everything over from my 5.1.1. Project.
