PC Keeps booting to bios and NVME ssd not showing up in boot Priority anymore

[wegoodtbh]

Hello everyone so I am having trouble with main and only ssd at the moment.
 

So basically today all of a sudden my pc started booting into bios anymore and I can't get it to go into windows anymore. It was working just fine until today. My SSD shows up in storage configuration but not boot Priority, boot Priority is empty.
 

I think this may have happened after the PC was forced to shutdown. The power cable at the back of my pc was loose and I was taking it in and out while it was on (pretty dumb in retrospect please dont flame me for this) so that may have caused an issue. I'm not really roo sure where to start as my motherboard and SSD are not that common. Please help

 

Motherboard: ASROCK H670M ITX

SSD: Xpg gammix s70 blade

It hasn’t somehow jumped to trying to boot legacy over UEFI or similar in the BIOS has it?

 

Perhaps trying the optimised defaults in the BIOS will help.
