Cannot open Anki from the launcher

Version: 2.1.49
OS: Debian GNU/Linux 11
DE: Plasma 5.20.5

I cannot open Anki from the KDE launcher, but only from the terminal. I went into the .desktop folder and changed Terminal to true and I managed to get this screenshot.

Your distro doesn’t appear to have a locale setup correctly for GUI apps. Your distro’s forums may be able to help.
