Is the touchpad enabled, both in KDE settings and if there's a function key that will "lock" the touchpad?

Have you tried a different kernel, e.g. linux-lts ?

i tried lts still it wasn't working , I checked the touchpad settings from all settings there it was not detecting the touchpad

If this is a new model you could do the other way round, and try the linux-mainline, as newer HW could be better managed there.

Yes, although it was working in the live installer environment, so it should be supported by the 5.14 kernel... :thinking:

Can you boot the live environment again and find out what sort of touchpad it is?

whats is linux-mainline sir , I am new to linux so I dont know such terms

how can I check type of touchpad from live environment

Open Garuda Settings Manager, Kernels, push Refresh and you'll see a list of installable kernels. But as notes above, I missed the fact that the touchpad was recognized in the live USB :blush:. But you could try anyway...
From the live USB, I think you could provide the output of:
lsusb
xinput
libinput list-devices
