there was another update to the firmware
renaming, moving away or deleting /usr/lib/firmware/rtw89/rtw8852b_fw-1.bin.zst should be enough to solve this issue until we get the 6.17 kernel
once we get the new kernel, we might need to reinstall linux-firmware-realtek if we don’t get a new version at that time.
this should confirm that you loaded the other firmware
