Erreur HTTP 500.19 - Internal Server Error (when publishing but not in Visual Studio)

I published a very simple ASP.NET Api on my Web Hosting Server. I have this error :

Error HTTP 500.19 - Internal Server Error.

Everything works well when I launch the api from Visual Studio 2019. Then I created a local website in IISExpress on my computer that uses local published files. I have the same error.

Module: IIS Web Core Notification: Inconnu Gestionnaire: Pas encore déterminé Code d'erreur: 0x8007000d Config Error:
Config File: \?\E:\CSharp\MyApi\MyApi\bin\Release\netcoreapp3.1\publish\web.config

Here is the web.config :

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2"   resourceType="Unspecified"/>
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\MyApi.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>

It works with Visual Studio so I think the problem does not come from the API, but some configuration. I already tried the solutions from the related question, like Install URL rewriting module. I'm stuck for fews days now, so please give me some help.
