my setup: WAN -> TL-r605 only 1 LAN port connected to switch -> T1500G-8T v2.0 -> computers and waps

So I was tinkering with tl-r605 through omada v4.2.8 controller
interface: wan only
source port: all of it
destination IP: to my test pc
destination ports: all of it

after creating and applying the rule the tl-r605 LAN port just gave up on connecting. the lan port on tl-r605 would light up for 4 seconds then disappear for another 4 seconds. it just keep doing that forever. my switch t1500g-8t v2.0 on lan port would not even light up anymore (connected to tl-r605) all other ports working fine. I restarted / re-adopt / restore previous configuration in the controller and the tl-r605 and the lan connection works but after how many hours the lan port would just stop working and the same 4 seconds green light on 4 second off would repeat forever. all devices connected had gateways connected to some random IP as tl-r605 could not be found

well I reset the tl-r605 and made it my third party router with a raspberry-pi behind just to see if the lan ever gives up again.so i replaced my tl-r605 it with my old stable tomato router and everything works just fine. am afraid to put it back to my main network

these are the only logs I could salvage during the whole time from 5:49 am to 7:45 am there is no internet

hope tp-link fixes this bug
