I'm afraid that I've never seen such error before. What happens if you deploy the same app using Visual Studio?

I get the same error when I deploy using Visual Studio

As far as I can see your application is .NET 6 - you need to have relevant .NET installed on your machine with the IIS.For other questions related to deploying Blazor applications with Visual Studio, IIS, what needs to be installed you can ask on official Microsoft forums or StackOverflow.
