.Net 8 Isolated upgrade issue- RPC Exceptions in .Net Core Function App

Hi Team,
Need Immediate help. I am continuously receiving RPC Exceptions when I have upgraded my Function App to .Net 8 previously I had zero exceptions related to this in .Net 6. 
Scenario:
We are creating builder with ConfigureFunctionsWebApplication() like below:

1. var builder = FunctionsApplication.CreateBuilder(args);

2. builder.ConfigureFunctionsWebApplication();

And basically, we have Http triggers and SB triggers in the application and only couple of them are facing issue and the error in AI states that this is an issue related to worker. I have copied multiple exception wrapped as an RPC exception below:

1. An exception was thrown by the invocation.
Exception: System.TimeoutException: Timed out waiting for the function start call.
2. The operation has timed out at Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore.DefaultHttpCoordinator.SetFunctionContextAsync(String invocationId, FunctionContext context) 
3.Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore.DefaultHttpCoordinator.SetFunctionContextAsync(String invocationId, FunctionContext context)
4. Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore.FunctionsHttpProxyingMiddleware.Invoke(FunctionContext context, FunctionExecutionDelegate next) in D:\a\_work\1\s\extensions\Worker.Extensions.Http.AspNetCore\src\FunctionsMiddleware\FunctionsHttpProxyingMiddleware.cs:line 45
