I tried it here; this time the error isn't from reading, but from
add-element "Attempting to add an illegal object to language". So this
means it really is the same problem as in bug#29220: that newly read
objects don't have the right type.
A quick demo:
(require 'eieio)
(defclass foo ()
())
(let ((print-circle t)
(foo-obj (make-instance 'foo)))
(cl-assert (foo-p foo-obj))
;; This assertion fails!
(cl-assert (foo-p (read (prin1-to-string foo-obj)))))
