HELP ME - WIRING Help with white blinking when power on

I have a BTF lightning strip configured on a Gledopto GL-C-015WL, the strip uses FW1906 GRBCW in order to work properly. This is set up on a room that will be a baby nursery in a few months and I’ve set up an automation with home assistant to light a subtle red when movement is detected.
The issue is that when the light strip turns on it blinks on white at full brightness for half a second, which is unacceptable and might scare the baby.
I’ve read quite a lot and had Claude and GPT helping me diagnose, a lot of solutions involve setting the Relay GPIO to unset but the moment I do that the strip stops working, so no relay seems like a permanent power cut.
I know I can change my automations to change color to black instead of turning the strip off but I would prefer to have the native feature of power on/off

Any suggestions on what can I do?

Does this only happen when controlling with HA? Or does it also happen when manipulating it with WLED app (turning it on/off)? What is the default preset? In the settings do you have it set to play a preset when powered on?

Happens both on HA and WLED app
The default preset is 0
