kglobalacceld is the global keyboard shortcut daemon, so based on that alone it looks to me like you added a custom keyboard shortcut and that’s broken. I’d try going to the keyboard shortcut settings, exporting the current shortcuts, resetting to default, rebooting the system and see if that solves the issue. If it doesn’t solve the issue, you can just import your shortcuts again and try something else, if it does work you can import your old shortcuts and do a little detective work to figure out which one is broken.
Edit: In your journal I found this
kded6[2423]: QDBusObjectPath: invalid path "/modules/plasma-session-shortcuts"
kded6[2423]: kf.dbusaddons: The kded module name "plasma-session-shortcuts" is invalid!
And here’s someone else who describes the desktop freezing and has the same lines in their log and they fixed it.

#QT_QPA_PLATFORMTHEME=“wayland;xcb” < I believe this was the problem
# GBM_BACKEND=nvidia-drm
# __GLX_VENDOR_LIBRARY_NAME=nvidiathese variables were added to try wayland before the explicit sync update for nvidia drivers and kde

I’m not 100 its solved but no issues since commenting those variables out
Might be worth a shot?
