I can't seem to edit my comment? Anyways more info (I restarted, and now it's back to normal behavior for now).

From KInfo:
Operating System: Garuda Linux
KDE Plasma Version: 6.1.4
KDE Frameworks Version: 6.5.0
Qt Version: 6.7.2

I also have diagnostic info from my distro's tool (garuda-inxi) here: https://bin.garudalinux.org/?3850f490d7354721#Ethdp3jmoxfEVtK5aFPoT1VhUer8v2auNFp8CZhCXEV9

Does launching apps via pinned Task Manager entries or launchers dragged to the desktop also not work when the system is in this state?

(In reply to Nate Graham from comment #2)

> the desktop also not work when the system is in this state?

Currently in this broken state, no cannot opened any pinned task manager entries from Icons only task manager widget, application menu widget, or the desktop. I can still use the system overall though, as I have Konsole open, and can launch any app from the command line.

Don't know if it's related or anything, also noticed when I was editing the icons only task manager, the configuration window opened up fine. Seems like it's just opening applications through plasma. Out of curiousity, also looked up how to launch desktop files, and was able to do `gtk-launch org.kde.konsole.desktop` in the command line without any issues. It's just launching applications graphically.

sounds like your systemd may be having trouble.

run

`sudo systemctl log-level debug`

then run 

`journalctl -f > /tmp/journallog`

then try to start something

then attach the file /tmp/journallog to this bug report.

Also you could run 

`QT_LOGGING_RULES="org.kde.*=true;kf*=true" kioclient exec https://kde.org/reusable-assets/home-blur.jpg`

and attach its output.

I don't know how to add attachments? Anyways, here's the journalctl log:

It also gave me the popup that `Unit app-firedragon@562cf680e1c4454c8be01ca766f81897.service not found.` Firedragon is the distro GarudaLinux's browser.

I've discovered that trying to open an appimage in this broken state freezes (and crashes?) plasma (have to restart afterwards). Launching appimage from command line is find though. Also sometimes it's weirdly conditional, gtk apps like firedragon (derivative of floorp browser, which is a derivative of firefox) and qt/kde apps can start normally, and electron apps can't start. Sometimes it's all applications though.

So after plasma 6.2, it went away for a while, and then came back. I've noticed some patterns: it tends to happen more when using the linux-zen kernel rather then the linux-lts kernel.

Also just had it happen right now in the middle of a session, after I tried exporting an image from Inkscape. Here's the journalctl logs:

It seems like for whatever reason it's asking for sudo??? no idea, kioclient exec is broken.

YAYYYY!
After more research finally came across this: https://forum.garudalinux.org/t/cant-start-any-app/37635/34
tmpfs was getting filled up, and seems like in general was only a problem on the garuda-linux distro. What I don't get is why this only seemed to happen on Plasma and not Hyprland, but who knows. After clearing tmpfs, everything works again!

Sorry to have bothered all of yall awesome KDE folks! Love everything amazing y'all do, and thanks for any previous help! Solution was posted here, in case anyone comes across this in the future: https://forum.garudalinux.org/t/cant-start-any-app/37635/36.

Thanks so much for the kind words!
