You need to run the filesystem check from a live system or unmounted partition.
So either go into a tty (logout your normal user from plasma to not screw stuff around) and login as user and switch to root with and sudo -i and run then or use the live system to boot up and run without prior mounting this partition.
As far as I remember you have a ecryptfs home partition and are not using full disk encryption (LUKS) on home.
So that means its a normal filesystem to check.
Lets try this and hopefully that is the only issue here.
Otherwise I am completely out of ideas as it makes no sense to suddenly appear with no update responsible for this issue.

Code:
umount /dev/sda3 && fsck.ext4 /dev/sda3

sudo fsck.ext4 /dev/sda3
