Did you have custom code you missed when upgrading your project?

Your error message is pretty vague so you might want to check the IIS event logs or the regular computer event logs.

I worked on a case with the same issue two days ago. Make sure the Roslyn compiler NuGet package is installed

https://docs.kentico.com/k11/installation/upgrading-to-kentico-11

Required .NET Compiler Platform

Kentico 11 requires the .NET Compiler Platform ("Roslyn") compiler to run. Installations of Kentico 10 or newer contain the Microsoft.CodeDom.Providers.DotNetCompilerPlatform NuGet package by default, which provides the required functionality.

However, if your project is upgraded from Kentico 9 or older, you may be missing the package. In these cases, you need to install the package before applying the upgrade:

Open your Kentico solution in Visual Studio.
Right-click the main web project in the Solution Explorer and select Manage NuGet Packages.
Install the Microsoft.CodeDom.Providers.DotNetCompilerPlatform NuGet package (version 1.0.2 or newer).
