Hi Nasser! I cannot reproduce the AttributeError integrals - on my computer they eventually fail with an ECL memory limit error.
I'm quite sure that the problem is the same as with the explicit roots - there is no sagemath equivalent for fricas' implicit roots, which is https://github.com/sagemath/sage/issues/32143.
