Lenovo FLEX-15 touchpad not working after windows update

Hello,
My Lenovo Flex 15 touch pad is not working after windows 10 update.
The exact model is: Lenovo FLEX-15IWL Laptop (ideapad) - Type 81SR
I am using Windows 10 HOME Edition.
Bios Version: ALCN32WN(V2.09)

Issue Is:
Touchpad not working and
I am suspecting the reason is - I2C HID DEVICE driver in Device manager is with 2 entries (1 with exclamation mark)

Steps already did:
- I Tried to update driver from device manager, uninstall that driver from device manger but after every restart it became same (2 entries -1 with exclamation)
- I tried to disable One I2C HID Device and try restarting but still touchpad does not work
- I tried to update drivers and BIOS from Lenovo support page still touchpad does not work
- I did hardware diagnostic test from Lenovo support it does not show any issues in that as well.
- Finally, I tried to reset my windows 10 with save data option but touchpad does not work then I formatted windows with all data removal option, but still touchpad does not work.

Can you suggest me anyway to resolve this touchpad issue.

Thanks
Kan

Your log shows June 19, 2021 as when Windows 10 Home Version 20H2 Build 19042 64-bit was installed.
I re-read post #1 and saw the above comment from you that I didn't notice before.
Are you saying you did a "clean" re-install of Windows 10 today, and afterwards your laptop's touchpad still is not working?

What's the exact serial number on your Lenovo FLEX-15IWL Type 81SR Laptop?
Which country was it purchased in?

Serial Number is: MP1JACXA
It was purchased in U.S.
THIS is the Lenovo support site for your laptop which was purchased in July 2019 and came with Windows 10 Home 64-bit.
You should add and save this site in your browser favorites/bookmarks list so you can quickly refer to it when needed.

THIS is the touchpad/pen/mouse driver for it.
Install it and then see if it resolves your touchpad issue.

Hello

I tried to install the driver but can not see the touchpad option in settings yet.
Can you please suggest something else.

Sorry for the late reply.
