As of 2020, is there any fix for 802.11w deadlock?

This is an old 802.11w issue that has been documented and it’s a very big issue as clients can be selectively attacked and enter a deadlock, where only disabling and re-enabling wifi solves the issue (in fact I’m currently experiencing these attacks from an unknown source).

So my question is if there’s a way to solve this problem or if there’s a new standard that already fixed it.

I currently have an ASUS RT-AC68U (stock firmware) with PMF set as required.
