Visual Studio Publish throws "MSB4018 The "ResolvePackageDependencies" task failed unexpectedly." - visual-studio

Question

I have a project that I used to deploy as a single executable, but I am no longer able to as the Publish process throws while trying to resolve the nugest. The project builds fine during the publish process and it also runs fine from visual studio.
My publish results:
========== Build: 7 succeeded, 0 failed, 1 up-to-date, 0 skipped ==========
========== Publish: 0 succeeded, 1 failed, 0 skipped ==========
I get a popup with this error:
08/12/2021 21:35:26
System.AggregateException: One or more errors occurred. ---> Microsoft.WebTools.Shared.Exceptions.WebToolsException: Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details.

And in the Error view I get this:

This is the configuration I am trying to build with:

Any ideas what is going wrong?
