After a recent update (not sure if that was the first including a new kernel 6.1) my ubuntu linux laptop cannot boot anymore
the error is
Volume group “ubuntu-vg” not found Cannot process volume group ubuntu vg IO error while decrypting keyslot. Keyslot open failed. Device /dev/nvme0n1p3 does not exist or access is denied Please unlock disk nvme0n1p3_crypt_ but then the usual decrypting code does not work
while in initram shell I noticed there were no device /dev/nvme* nor /dev/mappe* for my internal ssd
I managed to boot the laptop with a ubuntu live usb stick and manually decrypted and mounted my ssd partitions and my data were all there
so I rebooted then I made the grub boot menu to appear again and I selected the previous kernel 5.17, and the system managed to boot normally
Now I would like to fix the new kernel in a stable way
here are some info on my laptop:

$ lspci | grep Unassigned 03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader (rev 01) $ Should/could I also blacklist the drivers
blacklist rtsx_pci blacklist rtsx_pci_sdmmc in /etc/modprobe.d/blacklist_rtsx.conf and rebuild the initramfs?
I am asking since I am quite worried to brick the system
Apologies if I used terminology incorrectly or asked dumb questions.
