[SOLVED] ath10k_pci crashes when changing wifi network

Whenever I try to change the WiFi network and it was connected to another network ath10k_pci crashes. The only way to reconnect to WiFi is to turn the adapter back on. This issue occurs through nmcli and the gnome ui.

$ nmcli device wifi connect [ssid] password [password]
Error: Connection activation failed: (4) The device could not be readied for configuration.

$ dmesg |grep "ath10"

Re: [SOLVED] ath10k_pci crashes when changing wifi network

An update:
I didn't find the cause of the issue, but I found a workaround. I just installed iwd and configured NetworkManager to use iwd and now it works without crashing.
