Both Bootcamp and MacOS partitions unable to open

I’m locked out of my MacBook Air 2016 due to the firmware password. I remember seeing it a few days ago, but I don’t remember setting it, and it’s none of the passwords I normally use. The nearest Apple Store is hours away. Any startup command I try lead to the file with the question mark. I had installed bootcamp on a usb hard drive but it leads to the recovery loop in windows so I can’t even access that and get stuck on the blue logo screen. The options that window gives to recover do not work. I was thinking since I can’t get into Mac, I could try fixing the bootcamp usb but I have no idea where to begin. I have another Mac in case I need it to fix the usb. I’d appreciate help thanks!l
