Information panel

Dolphin crashes when trying to use the information panel to play videos or view images.
I have attached a photo showing the actions that lead to the closure of Dolphin.
When running Dolphin in the console, after the crash there are no errors in the output.
The Dolphin window simply closes.

If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl?

Thanks!

The thing is that it doesn't give any error.
The Dolphin window simply closes when you click on the playback button.
This problem has existed for a long time.
I don’t remember exactly, but I think this problem happened last fall.
I hoped that it would be fixed in each new version of Dolphin.
I checked on Fedora and Neon, and the behavior is the same everywhere.
I’ll try to check it on Neon, maybe there will be an error message there, and I’ll be able to create a backtrace.

Looks like I messed something up.
It turned out that I had this problem because of the default phonon-mpv engine.
https://github.com/OpenProgger/phonon-mpv
Set the default engine to phonon-vlc, and the problem disappeared.
For more than six months I could not understand why this failure occurred.
Thank you.
