After attempting to configure IIS as a replacement for IIS Express, both stopped working and delivered the above error on deploying the .NET Core project in VS2019. According to IIS anonymous authentication is enabled, I also entered explicit user name and password as well as giving my user all rights to work with the project's directory. I restarted the IIS several times and re-created the pools and Pages, as well as repairing VS2019 in hope to get the IIS Express running again at least. I have no idea what else I could do.
EDIT: I am using IIS10

You can try the following steps to solve your problem:
I was able to figure it out myself by now:
For some reason during setting up the IIS and IIS profile (accidentally or by some quirk of VS), the anynomous authentification setting was set to false
. Which also affected the IIS Express to not work properly anymore. Simply enabled anonymous authentification resolved the issue for both.
Project Properties
-> Debug
-> IIS profile
-> anonymous authentification: ✓
