Hi,
I have a problem with application start. My config:
OS: EndeavourOS x86_64
Kernel: Linux 6.17.5-arch1-1
DE: KDE Plasma 6.5.0
App installed with 'Joplin_install_and_update.sh'
AppImage desktop app not starting. It doesn't display any error message and not producing a crash report in '/home/user/.local/state/'
Only was able to find this message in 'log-cross-app-ipc.txt':
2025-10-28 21:02:14: Starting server using secret key: /home/user/.config/joplin-desktop/ipc_secret_key.txt

Please let me know what additional info I can provide to help to clarify the issue.
Thank you
I have the same problem and without tinkering with the .json file, what I do is just make sure Joplin isn’t maximized when I close it. Otherwise, the process launches but there is no window. So I terminate the process in btop, and then, it launches fine, even maximized… but I have to make sure it’s not maximized when I close it, or I have to do it all over again.
Weird bug. I think it’s related to KWin under Wayland, because like TexZeTech said, it runs fine under X11 and I might also add that I also tried mutter (GNOME) under Wayland and there’s no problem there either. So, definitely KWin + Wayland.
