and see if there's a previous version of the kernel you can roll back to. In case you have an older kernel without this issue like the 6.6 or 6.5 releases, you can reboot and select the older one from grub. If not, you can pull a working kernel from backports with
reboot, and the newly installed kernel should boot by default. If not, just select it from the grub menu.
