4.0 regression: pressing F10 causes crash / assertion failure

Hi all! « /opt/shlomif/vlc-git-master/bin/vlc https://www.shlomifish.org/Files/files/music/mp3-ogg/10%20-%20Rogue%20Nation.ogg » crashes on fedora 32 x86-64 after I press "F10" (someone was able to reproduce it on his archlinux system too and it also happens to me on mageia 8 x86-64).

I will attach a gdb stacktrace.

I built vlc like this

#!/usr/bin/env bash
p="/opt/`whoami`/vlc-git-master"
export LUAC="/usr/bin/luac"
export CFLAGS='-g'
./configure --prefix="$p" --with-kde-solid="$p/share/apps/solid" --enable-debug --disable-schroedinger --enable-debug --disable-opencv

The assertion error is:

vlc: config/core.c:120: config_GetPsz: Assertion `p_config != NULL' failed.

It happens with any media file I tried (.ogg, .mp3, .webm, etc.)

my system is:
