dotnet watch crashes with "The WebSocket is in an invalid state ('Aborted') for this operation. Vallid states are: 'Open, CloseReceived'"

[rogihee]

Describe the bug

After receiving instructions to try to reproduce #47392 , me and our colleagues run dotnet watch with procdump attached to catch any errors.

This exception "The WebSocket is in an invalid state ('Aborted') for this operation. Vallid states are: 'Open, CloseReceived'" is our most common one.

Here is the procdump file:
dotnetWatch.dmp

To Reproduce

Difficult as it occurs random in our workflow.
