TP-Link Kasa KL125 bulbs unreliable within HA since 2024.10.2

I have 11 kasa KL125 bulbs and since 2024.10.2 (I skipped 2024.10.0 and 2024.10.1 releases) they've been going offline in HA. In the app they are always online and consistently immediately responsive. The fact that the app works instantly on all bulbs that show offline in HA tells me that this is definitely a HA integration thing.

One person in another thread mentioned changing IPs in dhcp, but I've since migrated all to static IPs.

This is what I see in home assistant. Again, all of these have solid signal to the access point, and are available in the kasa app and instantly respond to changes from kasa.

Some of the behavior I see when using the homeassistant is:

When turning on or off a group of 4 bulbs I see the following behavior

Not all will toggle usually 2 or 3 out of 4 One may blink at full brightness for about a tenth of a second every 3 to 4 seconds Sometimes they come on a different brightnesses When adjusting individual bulbs Long delays before responding Bulb immediately reporting offline Bulb coming on at partial brightness when instructed to turn on at 100%

Code for my toggle call

metadata: {}
data:
  brightness_pct: 100
target:
  area_id: office
  entity_id: light.office_lights
action: light.toggle

light.office_lights is a group entity containing office light 1-4

Adding log entries - I see a bunch of this over and over with all of my bulbs:
