I have the same error but different firmware used on iwlwifi module. It's the same network card. It crashes in a few minutes of use and reveals a slow network connection and packet drops. I can't even test network speed by speedtest.net because the test is ending with an error. Ubuntu 23.10 here.

The access point is a Teltonika RUT 241 running firmware 00.07.06.8. It's an OpenWrt derivative. I'm not 100% sure about security implications. The driver restarts and chip seems to work OK after that, but I had one case when it started acting up afterwards. Not sure if a rogue AP could affect this somehow for DoS or otherwise.
