Migrating from .net 8 to .net 9 error

i successfully update radzen studio and radzen studio for visual studio. I can do everything except publish my app. After the publishing process, the web site tries to load and the browser shows a 500.30 error. I've tried to resolve it but nothing seems to work. Did anyone get this error?

This error means that the app failed to start. Check what version of .NET you have installed on your IIS - you need .NET 9 Windows Hosting Bundle:
