Why Blazor WebApp signalR crashes when large string is sent to UI?

While sending a large file data, streamed as a string from my backend to frontend, the blazor app crashes with the attempting to reconnect to server error. The app crashes when the file is loaded as a string successfully and right before sent to the ui.

I suspect the signalR is being disconnected. Any idea how do I fix this?

I Expected it to send the data to the UI successfully. I could not see any error from my logs during the app crash as well

My LoadFile() method is shown below:

 private async Task LoadFile(string file)    {        isFileLoading = true; // Start spinner        selectedFile = file;        InvokeAsync(StateHasChanged); // Ensure UI updates again        await Task.Yield();        try        {            //await Task.Delay(2000);            if (OnFileSelected.HasDelegate)            {                await OnFileSelected.InvokeAsync(file); // Invoke parent's method            }        }        finally        {            isFileLoading = false; // Stop spinner            selectedFile = string.Empty;            InvokeAsync(StateHasChanged); // Ensure UI updates again            await Task.Yield(); // Reset after loading completes        }    }
