Hello Steven Kroll, thanks for posting this in our community. This is a frustrating situation, especially when BitLocker is preventing access and the keyboard isn’t responding.
If your keyboard isn’t working on the BitLocker screen, it may be due to lack of USB support during pre-boot. Try using a basic wired USB keyboard instead of a wireless or Bluetooth one. Connect it directly to a USB-A port if available, or through a powered USB hub if you're using USB-C.
Kind regards,
John Oli
