…vate ErrorOr(List errors)

private ErrorOr(List errors)
{
if (errors is null)
{
throw new ArgumentNullException(nameof(errors));
}

if (errors is null || errors.Count == 0)
{
	throw new ArgumentException("Cannot create an ErrorOr<TValue> from an empty collection of errors. Provide at least one error.", nameof(errors));
}

_errors = errors;

}

This check is unnecessary due to the one performed just above.
