There are several changes between 6.10 and 6.11 that drop support for
older firmware. I found at least:
https://git.kernel.org/linus/bec2cdf548f92641f68677fcc43dc19aa4d0eceb
https://git.kernel.org/linus/2cbeb1a38758bfd165a7f284933e24b4552da65d

I think the right firmware for your hardware is
iwlwifi-QuZ-a0-hr-b0-XX.ucode. With the above bumps, XX must be 77.
I would expect something like:
iwlwifi 0000:00:xx.x: firmware: failed to load
iwlwifi-QuZ-a0-hr-b0-77.ucode (-2)
in your kernel log.

This version of firmware-iwlwifi however only ships the files for XX =
50, 59 and 72.
So please try updating your firmware-iwlwifi package to at least
20230625-3~exp1.
If that doesn't fix your problem, please provide a full kernel boot log
of the broken configuration. (And if that fixes it for you, please also
report back that this bug can be closed.)
Best regards
