Adding an exception handler solved my issue when trying to get a thumbnail from a page when the above error occurs.

document.DocumentUnhandledException += GetDocumentThumbnail_DocumentUnhandledException;

private void GetDocumentThumbnail_DocumentUnhandledException(object sender, DocumentUnhandledExceptionEventArgs e)
{
MessageBox($"The document is corrupted and some pages cannot be loaded: {OriginalFileName}: " + e.Exception);
e.Handled = true;
}
