Heard a 'pop', CPU spiked to 100%, and will no longer playback or repond

So I was recording something the other day nothing out of the usual. When I heard a loud POP then everything died. Studio One stopped responding, the CPU spiked to 100% (in DAW but not in task manager) and I wasn't even using more than 10% when this happened.

My 6i6 is set up in the settings menu and even when I restart my computer I open a project (any project) and the CPU spikes to 100 and the play button will work but the navigator doesn't move and there is no sound.

Studio One 3 Pro
