Runtime error when starting on Azure Web App

[Cr3ature]

It works as intended on a local machine, but on a web app (win-X86) it breaks the start of the application.

This was tested within a .NET 5 framework Blazor WebAssembly APP with a .NET Core server host.

Error message:

HTTP Error 500.30 - Internal Server Error
The page cannot be displayed because an internal server error has occurred.
Most likely causes:

• IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
- IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
• IIS was not able to process configuration for the Web site or application
• The authenticated user does not have permission to use this DLL.
• The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.

Things you can try:
Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.
