iwlwifi broken after 5.5 upgrade

Hello everybody,
I own an Intel Wireless Card, which, according to lspci -nn goes by the name of:

03:00.0 Network controller [0280]: Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] [8086:24fb] (rev 10)

and, after the upgrade to kernel 5.5 and 5.5.1 I get the following error on dmesg and no WiFi network is seen in the NetworkManager:

Is there anything I can help you with in order to debug?

Thank you very much,
