Try this in ASP NET Core to avoid win32 exception:

private void CreateWorkbook(string fileName)
{
    using (var p = new ExcelPackage())
    {
        p.Workbook.Properties.Author = "Barry Guvenkaya";
        p.Workbook.Properties.Title = "MyTitle";
        p.Workbook.Worksheets.Add("MySheet");
        var bin = p.GetAsByteArray();
        File.WriteAllBytes(fileName, bin);

        // Below code opens the excel doc
        var proc = new Process();
        proc.StartInfo = new ProcessStartInfo(fileName)
        {
            UseShellExecute = true
        };
        proc.Start();
    }
}
