Deploy ASP.Net MVC web app to IIS with 403.14 Error

I'm using .NET Framework 4.8 and tried to deployed my web app to IIS but it showed the 403.14 error.
HTTP Error 403.14 - Forbidden
The Web server is configured to not list the contents of this directory.
And then I enabled directory browsing. This time, it showed the directory listing instead. As I clicked the "Views" folder, it returned another error.
HTTP Error 500.21 - Internet Server Error
Handler "BlockViewHandler" has a bad module "ManagedPipelineHandler" in its module list
I have been finding solution for days but none of them worked...
EDIT: I started a new MVC project and tried to depoly it. It works perfectly. But it broke once I added new database using entity framework. Just guessing the problem comes from the database. Is there any configuration if I want to deploy a MVC app with db?

IL Rewrite to mscorlib crashing w3wp.exe

I have built the IL Rewriter to monitor any file is being opened in ASP.Net WebApp. To do so, I am rewriting IL for a private method called 'Init' in FileStream class in mscorlib. Here, I inject the epilogue/prologue to register a custom callback.
Injection is working fine. Custom callbacks are also getting called whenever a file is getting opened in Windows Application.
But, when I do the same for ASP.Net web application, it keeps crashing with the following error -
System.ExecutionEngineException was unhandled
Message: An unhandled exception of type 'System.ExecutionEngineException' occurred in System.Web.dll
I don't understand if it is working fine with .Net-based Desktop Application, then why it does not work with .Net-based web application i.e. ASP.Net. What is the difference between Web and desktop application?
Googled for above error does not yield any solution :(

ASHX Page Compilation Error

I have a simple .net site built in 4.5 and I have added one web service reference to a SOAP endpoint. The ASHX page works fine in visual studio test server but when I copy to server 2012 server I get this error:
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: BC30002: Type 'QTWebService.VehicleInfo' is not defined.
I am confused because this type is contained inside the service reference. What am I doing wrong here? The site runs fine with the dev web server but copy to server 2012 and boom.
Thanks
