Regular kernel panics when connecting to new WiFi 7 wireless router

I've recently changed to a new wireless router with WiFi 7 and I've been having kernel panics ever since. I'm on the latest linux and linux-firmware version for arch.

Here is the panic report for one of the times it showed me a QR code: https://pastebin.com/yMXbNESg

I couldn't retrieve the journal logs for that specific boot but here is the logs for one of the other boots where a kernel panic happened: https://0x0.st/P_h3.txt (It's very large)

Here is my WiFi card:

lspci | grep -i net
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller (rev 0e)
02:00.0 Network controller: Qualcomm Technologies, Inc WCN785x Wi-Fi 7(802.11be) 320MHz 2x2 [FastConnect 7800] (rev 01)

Firmware version:

sudo dmesg | grep fw_version
[    5.216624] ath12k_pci 0000:02:00.0: fw_version 0x110cffff fw_build_timestamp 2025-06-25 09:26 fw_build_id QC_IMAGE_VERSION_STRING=WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3

I've tried using linux-lts and the kernel panics still happen. I feel like it happens less frequently on linux-lts but nothing concrete.

Any help for debugging this would be appreciated.
