Mac Studio keeps changing the main monitor on boot-up

I have a 2023 Mac Studio with 5 monitors (1 HDMI, 4 Thunderbolt). I am running Mac OS 14 (Sonoma). Whenever I boot-up the Mac, the main monitor is set to a screen other than the main monitor. This is incredibly annoying as I have to unplug the other monitors at random until the log-in screen appears on the main screen

What I have tried:

Disabling:

Automatically rearrange Spaces based on most recent use

and

Displays have separate Spaces

Mac Studio, macOS 14.2

Have you found a fix for this? My Mac Studio is doing the same thing.
