I cloned a project from a friend off of GitHub and after turning off debug symbols to squash another .NET error, I’m getting this. This project was building fine a week ago

C:\Program Files\Mono\lib\mono\msbuild\15.0\bin Microsoft.Common.CurrentVersion.targets(2074,5): The "ResolveAssemblyReference" task failed unexpectedly. 

The tooltip is too big to show the full error see image:

Tooltip error too big

How do I fix this error? Seemingly it has to do with .NET or dependency version incompatibility when I search online.
