[BUG] Crashing on start - Ubuntu 24.04

[GAS85]

Hello, app simply crashed on a start. If I start it from the CLI, then following errors seen:

$ qr-scanner 

(qr:48997): Gtk-WARNING **: 13:38:24.592: Theme parsing error: gtk.css:1422:23: 'font-feature-settings' is not a valid property name

(qr:48997): Gtk-WARNING **: 13:38:24.594: Theme parsing error: gtk.css:3308:25: 'font-feature-settings' is not a valid property name

(qr:48997): Gtk-WARNING **: 13:38:24.595: Theme parsing error: gtk.css:3770:23: 'font-feature-settings' is not a valid property name

(qr:48997): Gdk-ERROR **: 13:38:24.735: The program 'qr' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc'.
  (Details: serial 363 error_code 11 request_code 149 (unknown) minor_code 2)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
