Azure Functions .NET Isolated QueueTrigger not firing (no errors)

My QueueTrigger function never fires in my deployed function application (I have not tried simulating the queue locally yet). Messages are successfully written to the queue, the function app starts up without errors, and logs don’t show any warnings or failures. The function is discovered (shows up in the Functions list on startup), but it doesn’t process new or existing messages.

The only mention in the logs of this trigger mentions a noop listener. Stopped the listener 'Microsoft.Azure.WebJobs.Script.Description.FunctionGroupListenerDecorator+NoOpListener' for function 'processor-queue-grant'

using Microsoft.Azure.Functions.Worker;

public class ProcessGrantQueue
{
    [Function("processor-queue-grant")]
    public static async Task Run(
        [QueueTrigger("meta-grant-jobs", Connection = "AzureWebJobsStorage")] string message,
        FunctionContext context)
    {
        // ...implementation...
    }
}

I am using Microsoft.Azure.Functions.Worker.Extensions.Storage.Queues 5.5.3 for the QueueTrigger attribute.

I have my connection environment variables setup

• AzureWebJobsStorage__queueServiceUri = https://<account>.queue.core.windows.net
• AzureWebJobsStorage__tableServiceUri = https://<account>.table.core.windows.net (used elsewhere)
• AzureWebJobsStorage__clientId = <user-assigned-managed-identity-client-id>
• AzureWebJobsStorage__credential = managedidentity

My managed identity has the following roles on the Storage account:

• Storage Queue Data Contributor
• Storage Queue Data Message Processor

I can write to the queue without issues from a different function.

I have been searching a solution to this for hours but I can't really find anything that I have not already double checked.
