Hi @Brandon Dickinson , Welcome to Microsoft Q&A,
Assuming you are using Visual Studio,
If this is your first time using Visual Studio, it is recommended that you check whether .Net Framework 4.8 in the installer is installed correctly.
Secondly, you can try to see if the path length in your working path is too long and try to use a shorter path.
Finally you can also try clean project, then retargeted from 4.8 to 4.7.2 and back.
Here is a similar question.
Best Regards,
Jiale
