Downgrade Kernel 5.19 to 5.15

I'm having issues with my GPU on my laptop after installing ubuntu 22.10 with the 5.19 kernel ("VM_L2_PROTECTION_FAULT_STATUS:0x00140051"). My Lapotp freezes after a while and I'm also not sure when or how to reproduce this, those freezes come in randomly. Apparently it's a common problem known for ideapad 3 laptops with amd gpu. One suggestion was to downgrade the kernel. Does anybody know a well-explained guide, something beginner-friendly on how to downgrade the kernel from 5.19 to 5.15 without deleting the entire SSD and clean installing an LTS version of the OS?

Edit: Related to the freezes i experience, this is the error/warning I get:

sudo apt install linux-image-5.15.0-58-generic linux-headers-5.15.0-58-generic

Then, reboot the computer and choose the kernel in the grub menu.
