Wifi device suddenly vanished on ASUS TUF laptop

I have an Asus TUF565GE-BQ165T running Ubuntu 19.04 since june and every thing was (almost) fine until today when the wifi interface suddenly vanished while I was working. Wired connection works fine. I remember I already had a similar (not sure it was the same) issue and I found a one line solution here but stupidly I didn't think to write it down. As I'm not a low level expert, I'm a bit lost...

No wlan device

What I've checked so far:

Hardware check: It looks like the hardware is detected:

Module check: looks like modules are here

maurycy@kali> sudo lsmod | grep wifi
iwlwifi 315392 1 iwlmvm

rfkill doesn't help

aurycy@kali> sudo rfkill list

maurycy@kali> sudo rfkill unblock wlan

EDIT as per chili555 comment request. Lines 5 and 6 doesn't look to smell good, right ?

Edit 2: Problem solved without a real solution...

Actually, the laptop is in dual boot, so I tested with windows and wifi worked without problem. Rebooting on Linux "solved" the problem as I got the wifi device and the network back. Yet I don't consider that as a real solution...

The boot logs show the following:
