I have a possible solution that works for me on PC with Wifi. So maybe it'll work for others...
Having a really fast connection was causing the issue for me.
So I disabled 802.11ax (Wifi 6) in the wifi adapter which makes the PC use a slightly slower connection, but still plenty fast to game.
and since then, I haven't had the kicked for inactivity/disconnected from EA ect.
So for people on Ethernet or Console, it might be worth googling if you can do something similar to limit your connection speed, to see if it helps.
Hope this helps :)
Just coming back to say that this 100% fixes it for me. I've tried going back to wifi 6 after each update and the issue comes back. So people on consoles should experiment with changing your network connection to wifi, to phone hotspot, see if you can limit the connection speed in your router ect. On pc ethernet, maybe set the windows setting to make it a metered connection, as that'll limit the speed a bit.
