Blazor Wasm Crashes if another wasm instance is running in the service worker. #76026

Is there an existing issue for this?
- I have searched the existing issues
Describe the bug
My application loads another .NET Wasm instance in a service worker to perform offline processing. This causes the debugger to crash with
Microsoft.WebAssembly.Diagnostics.DevToolsProxy[0] DevToolsProxy::Run: Exception System.AggregateException: One or more errors occurred. (The remote party closed the WebSocket connection without completing the close handshake.) ---> System.Net.WebSockets.WebSocketException (0x80004005): The remote party closed the WebSocket connection without completing the close handshake. at System.Net.WebSockets.ManagedWebSocket.ThrowIfEOFUnexpected(Boolean throwOnPrematureClosure) at System.Net.WebSockets.ManagedWebSocket.EnsureBufferContainsAsync(Int32 minimumRequiredBytes, CancellationToken cancellationToken, Boolean throwOnPrematureClosure) at System.Runtime.CompilerServices.PoolingAsyncValueTaskMethodBuilder`1.StateMachineBox`1.System.Threading.Tasks.Sources.IValueTaskSource.GetResult(Int16 token) at System.Net.WebSockets.ManagedWebSocket.ReceiveAsyncPrivate[TResult](Memory`1 payloadBuffer, CancellationToken cancellationToken) at System.Runtime.CompilerServices.PoolingAsyncValueTaskMethodBuilder`1.StateMachineBox`1.System.Threading.Tasks.Sources.IValueTaskSource<TResult>.GetResult(Int16 token) at System.Threading.Tasks.ValueTask`1.ValueTaskSourceAsTask.<>c.<.cctor>b__4_0(Object state) --- End of stack trace from previous location --- at Microsoft.WebAssembly.Diagnostics.DevToolsProxy.ReadOne(WebSocket socket, CancellationToken token) --- End of inner exception stack trace --- at Microsoft.WebAssembly.Diagnostics.DevToolsProxy.Run(Uri browserUri, WebSocket ideSocket)
This makes it impossible to debug my application with the service worker running.
The wasm instance loaded in the service worker uses https://github.com/unoplatform/Uno.Wasm.Bootstrap
Expected Behavior
The debugger should not crash.
