Joplin exiting without any error

Thank you for this great application, of which I’ve been a happy user for several months now! The problem started today, the application was working great till yesterday.

I use Joplin on Android and Linux. My problem is occurring on Debian Buster, here’s the output of uname -a:

Linux debian 5.6.0-2-amd64 #1 SMP Debian 5.6.14-1 (2020-05-23) x86_64 GNU/Linux

I think the version number is 1.0.33, but unfortunately I do not know, because I can’t get it to display a version number. I can say that I just updated it using the install script right now (0940 GMT Sept 3 2020). But the problem continues.

When I try to start Joplin from the command line or otherwise, the program simply exits without showing any error. The only messages on the terminal are as follows:

(joplin:26923): Gtk-WARNING **: 15:11:12.463: Theme parsing error: gtk.css:68:35: The style property GtkButton:child-displacement-x is deprecated and shouldn't be used anymore. It will be removed in a future version

In log.txt as well there is nothing that seems relevant, only:

What might be the reason this is happening?

Thank you again!

The 5.6 kernel used to have a problem with Electron apps, I am not sure if it has been patched up in 5.6.0.2
