Bluetooth not working with Intel AX200 on Ubuntu despite Wifi working

Question

My self-built computer won't detect any Bluetooth devices although it can connect with Wifi.

My AX200 uses this PCIe adapter. On the adapter, the light signaling Wifi is working is on but the bluetooth light remains off. Picture

Here's some terminal output:

sudo systemctl status bluetooth
● bluetooth.service - Bluetooth service
     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2022-06-15 07:53:46 PDT; 23min ago

             └─621 /usr/lib/bluetooth/bluetoothd

rfkill list
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

sudo dmesg | grep hci0
[    5.602650] Bluetooth: hci0: Found device firmware: intel/ibt-20-1-3.sfi

[    5.602690] Bluetooth: hci0: Firmware already loaded
[   58.234933] Bluetooth: hci0: Ignoring error of Inquiry Cancel command

I followed the instructions here for restarting the daemon

I tried using a different Bluetooth manager with the Blueman manager from here

I tried removing the Wifi card from the adapter then reinserted it, reinserted the PCIe adapter, and re-installing the antennas, but still having the problem.

Here are some pics of the setup. The USB part of the PCIe adapter is connected to the F_USB2 port if that matters.

Thank you!

Edit:

Here's the output of sudo dmesg | grep -i blue

Kernel version is 5.15.0-37-generic

My computer only boots up Ubuntu so no dual-boot with Windows.

Please add output of dmesg | grep -i blue. Is it a dual boot with Windows? — Pilot6, Jun 15 '22 at 19:35
Also, what kernel are you using? There was a bug report about Ubuntu running on kernel 5.16 and the same solution was offered by arch users on Reddit. First, create a new directory. Then, move all the firmware /lib/firmware/iwlwifi-cc-a0-xx.ucode to the new directory except for iwlwifi-cc-a0-48.ucode So, all the other versions of this that are not 48 need to be moved out. To be clear Move only the files iwlwifi-cc-a0[version.ucode] that you are isolating away from firmware loader in /lib/firmware/. — mchid, Jun 15 '22 at 20:06
Mentioned in the same bug report, it might not work for bluetooth in an x16 slot which is also mentioned in this answer. — mchid, Jun 15 '22 at 20:08
Added info asked in comments in edit above. Also the adapter is connected to an x1 slot — TryingToPC, Jun 15 '22 at 21:08
I've also tried moving all the iwlwifi-cc-ao-xx.ucode files except the 48 one but still having problem of not detecting bluetooth devices. — TryingToPC, Jun 15 '22 at 22:51
By 9-pin cable, do you mean the one connected to the F_USB slot? If so, yes @heynnema — TryingToPC, Jun 16 '22 at 20:05
