[SOLVED] WiFi disconnects when using prime-run

My laptop (MSI GF65-Thin, i5 9300H, RTX2060M, Intel Wireless AC9560) has been having that issue since yesterday. Every single time I run anything with prime-run to use the Nvidia GPU, my wifi disconnects. It reconnects again on its own once the Nvidia GPU is turned off. I had similar issues the first time I installed Arch on that laptop (though at the time it didn't drop, it was just unbearably slow), and turning wireless power management solved it, but it doesn't seem to do anything anymore, the connection just drops and I have to kill the task running on the Nvidia card.

Here's the dmesg log when that happens:

[  594.087758] xhci_hcd 0000:01:00.2: xHC error in resume, USBSTS 0x401, Reinit
[  594.087765] usb usb3: root hub lost power or was reset

[  600.861271] wlan0: authentication with 50:39:2f:15:a0:75 timed out

Here's the output for iwconfig wlan0:

wlan0     IEEE 802.11  ESSID:"Livebox-A070"
          Mode:Managed  Frequency:5.5 GHz  Access Point: 50:39:2F:15:A0:75
          Bit Rate=866.7 Mb/s   Tx-Power=22 dBm
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=51/70  Signal level=-59 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:4   Missed beacon:0

Things I've tried so far to correct the issue:
-Reinstalling the entire system
-Swapping wireless cards with my desktop
-Using older Zen kernel versions that I know worked before
-Using LTS and Arch kernel
-Uninstalling xf86-video-intel
-Downgrading linux-firmware
-Blacklisting bluetooth
-Disabling USB auto-suspend

None has worked. I'm really starting to get desperate and would really appreciate help solving this. I'm pretty sure the wireless card itself isn't the issue since the exact same thing happens after putting my desktop's card inside the laptop (everything's fine on the desktop).

Marking as solved. Restarting my router seems to have solved the issue.
