Hello,

This usually happens because the BitLocker pre-boot screen only has very basic USB support, so keyboards on USB 3.0 ports are not seen until Windows loads.

Power the PC off completely, switch your wired keyboard to a rear-panel black USB 2.0 port only (avoid blue or SS-marked ports and avoid front-panel ports), unplug other USB devices, then power back on and try typing at the BitLocker screen.

If it still does not respond, move the keyboard to a different rear USB 2.0 port and try again. Tell me what happens and I will guide you to the next step.

This changed nothing still in the same spot before and I move them to the regular non 3.0 non blue ports

Sorry to hear that.

I know this is a tedious step, but could you please try to grab another mouse or keyboard to see if it works? Most of the time it does, it depends on the peripherals model.

Let me know if you can do it just right now, if not, we can try another solution.

I tried with another keyboard and nothing but I don’t have a spare mouse so I will get one soon and try that if you figure anything out in the meantime time lmk

It's unlikely, but If your motherboard has the round PS-2 port on the rear I-O, borrow a plain PS-2 keyboard (or a USB keyboard that explicitly supports the little purple PS-2 adapter), power the PC fully off, unplug power for 15 seconds, plug that keyboard into the PS-2 port, disconnect every USB device including the mouse and any front-panel hubs, then power on and try.

That is so weird. I can see that you mentioned you enabled legacy USB, so, can you confirm if keyboard and mouse work on BIOS?
