If this settings key is renamed, such as in my example RAW_CONTAINER_NAME, this error goes away.
Steps to reproduce
To reproduce the first error, build this GitHub repo: https://github.com/mmckechney/semantic_kernel_askq. This code has a function project named DocumentQuestionsFunction. When there is a local.settings.json key of CONTAINER_NAME it gives the DataProtection error.
For the second error, you can create a new function project using:
func init --worker-runtime dotnet-isolated --target-framework net8.0
func function new --language C# --template blobtrigger --name funcReproedit the local.settings.json file to add a new item CONTAINER_NAME and add any value, but don't leave it empty
