I have narrowed this down to the exact setting which causes the issue, and it's
a setting in VLC. I don't know if the bug is specifically with vlc, or with how
VLC talks with dolphin.  The video file is irrelevant; it happens when  the "Qt
Interface" is enabled in VLC.

Precise steps to reproduce, done on a 100% clean new user I created for this
purpose. 

Dolphin version: 22.04
VLC Version: 3.0.17.4
KIO(if it's related): 5.93.0
KIO-extras 22.04

STEPS TO REPRODUCE
1. Open VLC
2. Within VLC, navigate Tools > Preferences > Show Settings, and switch the
radio button from "Simple" to "All"
3. Scroll to the "Interface" section, and select "Main Interfaces" 
4. Tick the checkmark for "Qt Interface", then save settings.
5. Close VLC entirely.
6. Open Dolphin, navigate to a video file, then right click it, and Open With >
VLC Media Player.
7. Close Dolphin

Result: Both VLC and Dolphin close.

I was going to report this for VLC as well, but after testing both via the
nightly snap package, and compiling the latest git version myself, I could not
reproduce the error on VLC 4.0....which is targeted to release by the end of
2022.

SO. for now, for anyone else who comes across this, just disable the qt
interface.
