Net7 Blazor + WebAssembly (Client + Server) + SignalR | Hot reload fail

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

Hot reload did not work using `dotnet watch --verbose run` on the sample project `7.0/BlazorWebAssemblySignalRApp` from https://github.com/dotnet/blazor-samples.git

dotnet watch seems to not able to connect to the browser :
`Connecting to the browser is taking longer than expected...`

The only change i made in this repo (testing and recommendation from old bug)

dotnet watch logs :

### Expected Behavior

I expect hot reload to work like other projects `BlazorWebAssemblyScopesLogger` or `BlazorServerEFCoreSample` in the same repo sample

`BlazorWebAssemblyScopesLogger` is working with net7 and net8

### Steps To Reproduce

run `dotnet watch run` over `7.0/BlazorWebAssemblySignalRApp/Server`

no need to edit something, dotnet watch show continusly the message `Connecting to the browser is taking longer than expected...`

### Exceptions (if any)

_No response_
