Unable to launch game on Steam due to secure boot error, worked before

As stated. Have BF6 on Steam. It was working absolutely fine for 2 days. Yesterday. It just didn't launch. 

The launch screen would come up and the bar would fill, but then a small secure boot error pops up and it just disappears.

I spent 10 hours yesterday and tried EVERYTHING on the troubleshooting and user suggestions.

Bios settings. Fresh install of the game and also windows. Nvidia settings. Unchecking DLC. Updating drivers. Even tried a VPN. Tried launching with internet off.

You name it, I have tried everything.

Like I said, I spent 10 hours straight troubleshooting and going through every step on every guide but for the past 2 days I have been unable to play the game.

What are my options?
