.NET 6 Blazor Hot Reload fails depending on the port specified for the application Url

[severity:It's more difficult to complete my work]
Using RC2 of .NET 6 I created a brand new Blazor project.

From a terminal I then launched the application using `dotnet watch`.

However, when I subsequently changed a .razor file, the terminal reported that the file had changed but then silently failed; no hot reload occurred.

Eventually I had to cancel the process (CTRL + C).

After trying various things to diagnose the issue I eventually tried changing the port in launchSettings.json.

When spinning up the project it had been assigned ports 7073 and 5073:

``` xml
"profiles": {
"TailwindStarter": {
...
"applicationUrl": "https://localhost:7073;http://localhost:5073",
...
},
```

I modified this to good old 5001 (for https) and tried `dotnet watch` again.

```
"TailwindStarter": {
...
"applicationUrl": "https://localhost:5001;http://localhost:5073",
...
},
```

Tried running it again and it worked!

```
watch : File changed: D:\Code\TailwindStarter\Pages\Index.razor.
watch : Hot reload of changes succeeded.

```
