Deco S4 performance drops from ~350Mbps to 22Mbps when experiencing an event recorded in System log.

Hi - having spent hours trying to figure out what was happening with the performance of my S4, I've narrowed it a single event that is repeatedly logged on my S4's system log:

This event is happening very rapidly and is set at "Error" severity level. The S4 mesh on reboot works for a few hours and then is rendered to its knees by this 'errant' MAC address (50:32:37:c8:db:40) which is an Apple TV 4K connected to my local network via wired Ethernet. By resetting the Apple TV and re-establishing the wired connection, it appears that I've disabled the Apple TV WiFi connection and these error messages have stopped and my performance has remained steady at ~350Mbps but it concerns me that a single misbehaving client could have such an effect on my mesh. Equally concerning is that my only form of diagnosiing the problem is deep down in the bowels of a system log that is only really accessible from the web interface and not the application.
Any ideas on what this exchange is and why it kills my S4 mesh? TP-Link - if you're reading this, fix the 'disassocaite' typo in the err.msg.

Hi, could you please help me check one thing:
Previously, the Apple TV is connected to the Wi-Fi of Deco and the speed of Deco dropped from 350m/s to 22m/s, then you find some error logs and disabled the wireless connection, and switch the TV to a wired Ethernet cable connection. Finally, the speed became normal, am I right?
The system log displayed the roaming behavior of the client and it is only seen on a device that did not support the fast roaming protocol.
Later if possible, you could still try to connect the TV to the Wi-Fi of Deco and turn off the Mesh technology of the Apple TV on the Deco APP.
