Fails to launch GUI on xfce4

I'm using vlc on Arch Linux, on xfce4 desktop environment. After upgrading to 3.0.x, vlc exits when I try to launch it with GUI. The terminal output to qvlc is

VLC media player 3.0.1 Vetinari (revision 3.0.1-0-gec0f700fcc)
Gdk-Message: vlc: Fatal IO error 2 (No such file or directory) on X server :0.0.

And in .xsession-errors, a line

(wrapper-2.0:1016): GLib-GObject-CRITICAL **: g_value_get_enum: assertion 'G_VALUE_HOLDS_ENUM (value)' failed

shows up after each attempt to run vlc.

The output of strace -f -s 100 qvlc will be attached, if that will help.
