Was playing Destiny earlier and this happened

At first I thought maybe it was the game screwing up somehow and so I exited out of it and loaded it back up again and it was still doing the same thing. So then I turned off my xbox and when I turned it back on it had 1 flashing red light and an E74 error code.

It lasted me just about 3 months shy of 7 years so I guess it was a good run. Apparently $79 to get it repaired/replaced from Microsoft.
