Can't get wifi card to work on Lenovo Legion 5 Pro 16ARX8

Hi everyone, this is my first post.

I recently installed Arch and I'm using KDE Plasma.
I'm running a Legion laptop, with a rtw89_8852ce wifi card from Realtek, with kernel x86_64 Linux 6.1.63-1-lts (if that helps), and when I run lspci I find:

Network controller: Realtek Semiconductor Co., Ltd. Device c852 (rev 01)

sudo dmesg | grep rtw also returns this:

[    2.727816] rtw89_8852ce 0000:04:00.0: loaded firmware rtw89/rtw8852c_fw.bin
[    2.728619] rtw89_8852ce 0000:04:00.0: Firmware version 0.27.56.13 (ebbe528f), cmd version 0, type 1
[    2.728622] rtw89_8852ce 0000:04:00.0: Firmware version 0.27.56.13 (ebbe528f), cmd version 0, type 3

rfkill displays this:

ID TYPE      DEVICE                 SOFT      HARD
 0 bluetooth hci0              unblocked unblocked
 1 wlan      ideapad_wlan      unblocked unblocked
 2 bluetooth ideapad_bluetooth unblocked unblocked

...but nmcli only displays my ethernet port:

enp7s0: connected to Wired connection 1
        "Realtek RTL8111/8168/8411"
        ethernet (r8169), E8:80:88:A5:B4:64, hw, mtu 1500

        inet6 ::1/128

        domains: write
        interface: enp7s0

Strangely, my wifi card WAS detected during the archiso install, and I could use iwctl to connect to a network, but now it's just gone.
I've tried updating NetworkManager, turning it on and off from systemctl, I've been banging my head against this for a week now and I can't figure it out.
Can anyone lend me a hand? Thanks in advance and sorry if I didn't mention some important details, I'm not entirely sure what else I need to provide for this post.
