Unable to find files and desktop settings after updating Kubuntu in the software center

I am using Kubuntu 21.04. I just update (not upgrade) Kubuntu from default software-center. After a successful update, I tried to access my local files stored in another drive (128GB), but that drive is now empty. It had around 128GB data in it. Not only this, after this update, my all data stored in /home/abhishek/ (13GB) and /var/www/html/(50GB). was gone(may be deleted or something else). My desktop settings and themes are also gone. I am using dual boot (Kubuntu + Windows 10). I restarted my PC and logged back in but unfortunately, Result is still same.

I was also working in a project, but I cannot find it now.

Is there any method to get this data back?

EDIT 1:

Edit 3:

Output of /var/log/syslog

Edit 4:

I had 50GB of data in /var/www/html/ which is the location of PHP projects and 12.9GB approx data in /home/abhishek/. I wondered why am I not able to see my data in /var/www/html/, /home/abhishek/ and ``/dev/nvme0n1p4` and why my system-settings has reseted, themes deleted, chrome sign-out. One more things when my update process was running, after 1 minute, Kubuntu hangs, So I restarted my laptop.

Eg, I was enabled tap-to-click with touchpad, but now tap-to-click is not working because I have to re-enable it again.
