HTTP/2 error code 'PROTOCOL_ERROR' (0x1) in .Net 8

I have migrated Azure function app from .net 6 to .net8. function app includes orchestrator trigger and activity triggers.and when I am running function app, when calling orchestartor trigger from function its throwing error like below.
### What version of gRPC and what language are you using?

### What operating system (Linux, Windows,...) and version?
Windows

### What runtime / compiler are you using (e.g. .NET Core SDK version `dotnet --info`)
.Net 8

### What did you do?
If possible, provide a recipe for reproducing the error. Try being specific and include code snippets if helpful.

### What did you expect to see?
Azure function should run without errors

### What did you see instead?

Make sure you include information that can help us debug (full error message, exception listing, stack trace, logs).

### Anything else we should know about your project / environment?

Start with the failing call at AZF_Amazon.cs line 24 and trace it through Microsoft.Azure Functions DurableTaskClient and Grpc.Net.Client.Internal. Reproduce the .NET 8 Windows Azure Functions scenario and inspect the HTTP/2 response that produces PROTOCOL_ERROR. Done means identifying a reproducible cause and confirming that orchestration-trigger calls complete without the protocol error.
