Debugger will not stay attached (Mac, .NET 6, Azure Function Core Tools 4.x)

## Issue Description ##
Attaching the debugger to an Azure Functions Core Tools running process (dotnet runtime - not dotnet-isolated) seems to attach for a second or two and then just detach with no errors/useful information reported.

## Steps to Reproduce ##
1. install Azure Functions Core tools
2. func init --worker-runtime dotnet
3. func new
4. select any function type *I selected HTTP trigger
4. set a breakpoint or two in the resulting generated function file (.cs)
5. func start --verbose *note the process ID from the output once the function is started
6. attach to running process with standard coreclr debugger configuration

## Expected Behavior ##
Debugger attaches to the underlying process and waits for breakpoints to be hit. (I.e. when you manually trigger the function via cURL/Postman against localhost)

## Actual Behavior ##
Debugger attaches for a few seconds and then detaches.
