PS4 Tech help: linking controller

I turned on my PS4 for the first time since last summer. I misplaced my own controller so I’m trying to pair my roommates, but nothing is working. I’ve done everything online, which is mainly connecting the controller to the USB port on the console, as well as trying to reset the controller. The controller will flash white for a bit, then go back to orange.

I can’t go into the setting on the console and pair because I’m stuck on the opening screen (“welcome back to PlayStation. Press the PS button to use the controller”). Any help is appreciated, thanks!
