New WiFi module -> bluetooth stopped working

Hi!

I've installed a new WiFi module (Intel Wi-Fi 6 AX200) into my Acer 5 Aspire A515-52 laptop as the previous module was rather glitchy. However, since then I can't make bluetooth work:

$ bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available

# systemctl status bluetooth
○ bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)
     Active: inactive (dead)
       Docs: man:bluetoothd(8)

Apr 09 12:43:12 acer systemd[1]: Condition check resulted in Bluetooth service being skipped.

I have followed the Wiki, but none of the suggested solutions have worked. Not even rfkill is showing bluetooth:

$ rfkill list all
0: acer-wireless: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

The next section on the Wiki hasn't helped much either. The directory /sys/class/bluetooth doesn't exist, the system can't see bluetooth at all, although the new WiFi module should have a bluetooth capability. (here are the specs)

However, modprobe bluetooth does seem to do something:

# modprobe bluetooth
# systemctl restart bluetooth
# systemctl status bluetooth
● bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)
     Active: active (running) since Fri 2021-04-09 13:01:52 CEST; 1min 52s ago
       Docs: man:bluetoothd(8)

        CPU: 13ms
     CGroup: /system.slice/bluetooth.service
             └─2966 /usr/lib/bluetooth/bluetoothd

Apr 09 13:01:52 acer bluetoothd[2966]: Starting SDP server
Apr 09 13:01:52 acer bluetoothd[2966]: Bluetooth management interface 1.19 initialized

After the modprobe, /sys/class/bluetooth was created, but otherwise the result is same:

$ rfkill list all
0: acer-wireless: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

$ bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available

Here are some details about my network:

$ inxi -n
Network:   Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169 
           IF: eth0 state: down mac: (MAC)
           Device-2: Intel Wi-Fi 6 AX200 driver: iwlwifi 
           IF: wlan0 state: up mac: (MAC)
           IF-ID-1: wg-mullvad state: unknown speed: N/A duplex: N/A mac: N/A

BTW, journalctl doesn't show anything, except for pulseaudio understandably complaining that it can't find bluetooth:

Apr 09 12:43:37 acer pulseaudio[635]: GetManagedObjects() failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

I am quite desperate for a solution. WiFi is working somewhat all right, sometimes (about every two hours) it randomly stops working and I have to turn the laptop WiFi switch off and on to make it work again. Maybe it's my laptop that's crappy. (will be getting a Lenovo next time, I promise!)

Could you please help?
