Touch pad and touch screen are not working after upgrading to ubuntu 22.04

I have laptop Acer spin 5 "Spin SP513-54N" and had ubutnu 21.10 installed on it. At first, the touch pad and touch screen were not working so I followed the instructions in this page and it fixed it:

sudo gedit /etc/default/grub
Add pci=nocrs to the end of the options for GRUB_CMDLINE_LINUX_DEFAULT. It should look something like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nocrs"
sudo update-grub

Later when I upgraded to ubuntu 22.04, touch pad and touch screen stopped working again When ubuntu 22.04 starts up before applying GRUB fix, I get this error:

Ubuntu starts fine but the touch is not working. But when I apply the fix, ubuntu 22.04 fails to start with this error:

I tried every fix I could possible find online but nothing works. plz help me with this issue as the computer is not usable without touch pad

Upgrading the kernel to 5.18:

wget
wget
wget
wget
sudo dpkg -i *.deb

Then everything works with pci=nocrs.
