Touchpad isn't detected after update

I’m using fedora 37, after updating my system and restarting my touchpad doesn’t work and it’s not showing under mouse and touchpad settings.

sudo dmesg | grep -i touch may give you an idea of if your system recognizes the touchpad, assuming word touch is used.

that command returns nothing.

Start by looking at:
journalctl -b -g hid
lsusb
sudo libinput list-devices
inxi -FJz

In the journal do you see anything complaining about i2c?

What do you mean?

If you run,
journalctl -b -g hid
do you see anything regarding i2c?

or just pastebin it.
