Yes, this problem was reported some time ago, it is related to a driver bug
when working with older firmware versions. We already sent a fix for that, so
to solve it there're two options - either take the latest firmware from [1] or
apply a driver fix from [2].
[1] https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
[2] https://patchwork.kernel.org/project/linux-wireless/patch/20230926165546.086e635fbbe6.Ia660f35ca0b1079f2c2ea92fd8d14d8101a89d03@changeid/
