Nano Cortex fails to boot up

I’ve encountered a problem when I try to boot up my nano cortex. I plug the nano cortex in as I’ve done many times before but this time after a few seconds of plugging in, the nano cortex goes into its « preboot phase » with the few lights showing as usual but it never goes into performance mode. After I’ve waited about a few minutes, half of the nano cortex lights up but all of the controls are unresponsive presumably because of the control lock (exit button feature) but it never boots up fully so I can’t connect it to my phone and am unable to figure out a way to fix it. The power supply doesn’t seem to be the problem since I’ve used it many times before and I’ve tried multiple different power supply and even via usbc but to no effects. I’ve also tried booting it up with nothing else connected but it still doesnt work. All the buttons are unresponsive and I can’t seem to find a way to factory reset it.
