I am re-writing this question with more debugging info because it's driving me crazy. I cannot pair with my Lenovo Thinkpad Trackpoint II keyboard anymore after removing it from the list of devices in gnome-control-center once. It asks me to enter the key PIN then press enter. I do it, and nothing happens. The keyboard blinks 5 times which means it's supposed to be paired. I have no soft or hard blocks for bluetooth in my rfkill list:
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
Wireless is currently soft-blocked because I turned off Wi-Fi after reading that it may help.
Nothing has worked. Here is the current buffer for systemctl status bluetooth:

As you can see, the MAC address of my keyboard is d4:e8:60:34:b6:7b. My PC is also named anonpc. When I run gnome-control-center -v, I often get this message:
Bluetooth: DEBUG: Not interested in device 'anonpc'
Is there something in the firmware preventing me from pairing again? I would like to factory reset the keyboard incase it's something in the firmware, but there doesn't appear to be a way to
Ubuntu 22.04.3 LTS x86_64 / GNOME 42.9 / 6.2.0-1011-lowlatency kernel
