Honestly baffled, this is what I expect to see:
If you want to try one final thing you can check if it works in the dev env.
Go Help > Copy dev mode command to clipboard then paste that in either a terminal or whatever thing openbox might have like dmenu. It will open a new Joplin instance unrelated to your main one with its own profile in .config/joplindev-deskop which will have no notes, no plugins, no nothing.
If it doesn't work there then I think your Joplin install is haunted.
