SFXCA log entry is created by the managed Custom Action.
When WiX runtime prepares the assemblies for execution it extracts them from the msi database and copies them in the temporary folder. I am guessing that in your environment it fails to do so.

Maybe something is tricky with the permissions.
You can try to execute msi elevated to verify that.

I successfully built a setup on Jul 19 from the latest nuget packages, now on a fresh install with nothing else changed I get the same error and can't get rid of it, something has changed 🤔
