Hi there, welcome to the forum.
Downgrading is possible, see below, but I'd rather install and use for a while linux-lts kernel.
Keep and keep updated the zen one, so every now and then you can boot with it and try.

thank you.
but i have cleared pacman cache which is required for kernel downgrading i think according to this archwiki post.

Use the downgrade command (Automation in that wiki Page).
And again think about the lts...

+1 to Filo's suggestion to use the LTS kernel. This will put you back on 5.15, which I am guessing will satisfy whatever your actual need is.
