My Switch crashed while it was charging. Now it is unresponsive.

Last night I was playing on my Switch, when out of nowhere it crashed, saying an error occurred. Now it won’t turn back on at all, no matter how long I hold the power button. The controllers still light up but the console is unresponsive.

I practically always have it plugged into the charger, and over the years the cord has gotten a little damaged. I’ve been needing to charge it at an angle for it to work. What concerns me is that my Switch was at 100% when it crashed.

Can anyone please give me suggestions?
