Bug description

The desktop client crashes upon opening its settings. When starting from a terminal, I see this:

QGuiApplication::setDesktopFileName: the specified desktop file name ends with .desktop. For compatibility reasons, the .desktop suffix will be removed. Please specify a desktop file name without .desktop suffix
nextcloud.gui.application: Migrating old config …
…
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Abgebrochen (Speicherabzug geschrieben)

Steps to reproduce

the desktop client has multiple clouds configured and used to work up until now, no changes except for OS updates
Have a fully updated Arch Linux (2024-10-12)
Start the desktop client (pacman -Q: 2:3.14.1-1)
Right-Click on Tray Icon, select "Settings"
1-2 seconds later, the client crashes

Expected behavior

Should not crash – yet: Is this an application or a system issue? Used to work fine before the latest updates.
