Comment 10 for bug 2068738

I had the same issue, similar hardware I have had to revert back to the previous kernel version 5.15.0.-107 there was some errors in the log that pointed at the AMD GPU

if you need to boot from the previous kernel you will need to tap shift when the device boots, go into advanced options and select

kernel .107 generic

I then changed my grub menu

sudo nano /etc/default/grub

changed

GRUB_DEFAULT=0

to

GRUB_DEFAULT="1>2" (this tells grub to boot into advanced options and then the second linux kernel image, .107 at least for me ) save the file

sudo update-grub

sudo reboot

The device then booted successfully into the working .107

then i removed the .112 kernel

sudo apt remove linux-image-5.15.0-112-generic

sudo apt remove linux-headers-5.15.0-112

sudo update-grub

I also put a hold on .112

sudo apt-mark hold linux-image-5.15.0-112-generic
sudo apt-mark hold linux-image-5.15.0-112-generic
apt-mark showhold

I then changed grub back to

GRUB_DEFAULT=0

I have attached a full log for the developers perusal
