The problem appears to be occurring when the base class is subscripted, not when it's inherited. I can reproduce this issue on Python 3.6.10 by just evaluating Base[T].

'del Base.__slots__' after Base is constructed seems to work around the issue, and allow Base[T] to be evaluated. Of course, Base is still slotted at this point, since __slots__ are consulted only when initially building the class.
