Just a little warning for everyone.. if like me you upgraded to KDE 5.24 as soon as the tumbleweed update hit.. please be aware that in some cases it may break your KDE configuration..
For example:
https://www.reddit.com/r/kde/comments/sohpop/plasma_524_freezes_on_splash_screen_after_upgrade/
If you do end up with a broken desktop in the shape of appearing frozen or acting strange (like I did) it can be fixed by simply resetting the KDE configuration.
If you're on X11 you can do so by:
Hit Ctrl + Alt + F2
Login to your regular account
$ init 3
$ mv .config .config-bak
$ mv .cache .cache-bak
$ mv .kde4 .kde4-bak
$ reboot
You should now be able to login successfully using KDE. Copy back other app configs after you get to a working desktop.
I believe it's an akondi or mariadb related bug, as even with fresh config I'm getting errors when trying to start kmail:

My best guess is this occurs when trying to upgrade the configuration, which causes a hang and in turn a broken desktop. I'm still investigating further, might have to also reset the database?
In any case, if you run into this and don't have a home directory backup (like me
EDIT: Kmail works after a reset.. if you use it, and it doesn't launch see here:

If you would like samples of my borg backup scripts, I can provide them. I always run a /home backup before system upgrades. (btrfs snapshots aren't great at protecting against drive failure.)
Tried rolling back to KDE 5.23.5 but after the upgrade attempt the configuration ended up broken there too (same bug then occurred on 5.23.5).
With that said, once the KDE config was reset, I could login to KDE 5.24 just fine (had it running for a day now, so far so good)
In my case, I don't backup my home directory because my OS install is on a NVME drive (/home too), which is BTRFS for / and ext4 for /home.
My actual "data" is stored on several spinning rust drives and then backed up across other spinning rust drives / computers. Even my games are stored on different SSD drives.
So, in my infinite wisdom figured I didn't need to backup /home since the data was expendable and didn't hold anything valuable.

In my case the OS is on a tiny 1TB NVMe drive so data is on other much larger drives :-).
The OS itself is only backed up with btrfs snapshots.
My view is if the boot drive fails, or the OS breaks beyond repair (unlikely) then it's just a fresh install and mount my luks encrypted drives. Job done, data restored and working system.
My data disks however are backed up once a day to other drives.
