I am seeing the same problem as in ticket 39588.
I am filing another ticket because I can't comment on that one (reasonable), can't follow it (would be nice), but also to add an important comment.
While it may be that the problem is in Regular Labs Sorcerer, it's not a component I have installed or used. It's either used by Akeeba explicitly or is in some lower level Joomla subsystem that Akeeba uses. So I don't think it's quite right to tell Akeeba users to work with Regular Labs on this.
