Pi Zero v1.2. Kiosk build, Help Needed.

hi all, I'm having issues with a bit of a niche build. I want to get my Zero to auto boot into a kiosk from power on, with no user intervention. im running the latest build of PiOS 32-bit Lite I'm aiming to use openbox and midori or luakit to achieve this. everything seems to go swimmingly until i come to set the autostart of openbox ChatGPT whilst has been pretty spot on for various other projects, seems to be struggling with this one. Its suggestions result in screen blanking half way through the boot process and xserver dropping out saying no screen found. Any help to get it all to play nicely would be greatly appreciated

It seems to be when i log in manually it works perfectly, whilst when setting B2 Console Autologin Text console, automatically logged in as 'pi' user via raspi-config it fails.

or if i set any kind of auto login
