Hi,
I have my .net core 8 MVC app hosted into IIS.
And I have installed the .net runtime, sdk, .net core runtime, etc.
Still I am getting this error. Please help.

Other options are opening the Windows Event Viewer and looking for any errors. Set the environment to development mode and enabling logging in the web.config then start the application. If you can remote into the web server, then try starting the application using the "dotnet myapp.dll" command line.

You could check it by using the event viewer -> application -> Check the error of the application pool name. Besides, you could also check it, by enabling the stdlogs to true inside the web.config.
