There have been several known issues with iwlwifi starting with kernel 6.11.5 and 6.12.2 after the introduction of fast resume earlier this year, related to AX200/201/210 cards, see e.g. 219447 – iwlwifi: ax201: can't connect after resume - loop of Not associated and the session protection is over already - CSA mode=1 related and 219597 – iwlwifi: iwlmvm: Intel AX200 crashes on resume from suspend. According to one of the devs ( 219597 – iwlwifi: iwlmvm: Intel AX200 crashes on resume from suspend) a bunch of fixes has landed in kernel 6.12.5. If I am not mistaken, the next TW snapshot will contain 6.12.6, if it passes openQA.
