Please check if the below steps would help to fix the issue:

Application Insights is added by Azure Functions automatically. You should not add the Microsoft.ApplicationInsights.AspNetCore package to an Azure Functions project as there might be incompatibility issues doing it that way. Instead, if you want to write custom telemetry use the Microsoft.Azure.WebJobs.Logging.ApplicationInsights NuGet packages located here as shown by the docs and those docs :

There is a Functions-specific version of the Application Insights SDK that you can use to send custom telemetry data from your functions to Application Insights: Microsoft.Azure.WebJobs.Logging.ApplicationInsights
