Http Trigger Fails to Start With net8.0-windows + Azure.Identity

#### Check for a solution in the Azure portal
For issues in production, please check for a solution to common issues in the Azure portal before opening a bug. In the Azure portal, navigate to your function app, select `Diagnose and solve problems` from the left, and view relevant dashboards before opening your issue.

When targeting net8.0-windows and the Azure.Identity package is installed (though not directly referenced), my http trigger fails to load. If I change the target to net8.0, it works. OR, if I remove the Azure.Identity package, it works. But with both of those it fails. Also, when I run it locally, it _works_. I wasn't sure if I should post this here or on the azure sdk repo, but since it works locally but not when deployed, I figured I would start here. I created a basic repo to reproduce the issue - see below for details.

#### Investigative information

These are from the test function I created to reproduce the problem:

- Timestamp: 2024-04-30T18:39:46.389 (issue is ongoing)
- Function App version: 4.33.1.22394
- Function App name: function-start-failure
- Function name(s) (as appropriate): Function1
- Invocation ID: (Function is unable to load)
- Region: Central US

#### Repro steps

1. Create new "isolated worker" net8.0-windows function app
2. Add an http trigger
3. Add Azure.Identity package
4. Deploy it (it works locally)

#### Expected behavior

Http trigger loads.

#### Actual behavior

Http trigger fails to load.

#### Known workarounds

Avoid using Azure.Identity. Change to net8.0 (not an option for me but does fix it)

#### Related information

Here is an example repo that reproduces the issue: https://github.com/Anchora-Solutions/FunctionStartFailure

And that is deployed to https://function-start-failure.azurewebsites.net

Also, here are the logs I've found for host startup:

Start with the linked FunctionStartFailure reproduction repository and deploy the isolated-worker app using net8.0-windows with Azure.Identity, then compare it with net8.0 and without Azure.Identity. Use the supplied host-startup logs as the failure baseline, especially the missing Microsoft.WindowsDesktop.App 8.0.0 message. Done means the HTTP trigger loads in the reported deployment configuration without the language worker restart loop.
