Issue using GNOME Boxes in proot mode with a different $HOME directory

Hi, I successfully built an AppImage (or ArchImage) of GNOME Boxes using JuNest.

The script I use to run it is this

#!/bin/sh
HERE="$(dirname "$(readlink -f $0)")"
export UNION_PRELOAD=$HERE
export JUNEST_HOME=$HERE/.junest
export PATH=$HERE/.local/share/junest/bin/:$PATH
export HOME="/home/$(echo $USER)"
mkdir -p $HOME/.cache
$HERE/.local/share/junest/bin/junest proot -n -b "--bind=/home --bind=/home/$(echo $USER) --bind=/media --bind=/mnt --bind=/opt --bind=/usr/lib/locale --bind=/etc/fonts" -- gnome-boxes "$@"

the script to build this is https://raw.githubusercontent.com/ivan-hc/Boxes-appimage/main/gnome-boxes-junest.sh
you can download it from https://github.com/ivan-hc/Boxes-appimage/releases/tag/continuous

What works

Once downloaded and without additional configurations, by running it you are able to download/install operating systems and those from any ISO you stored, without problems.

What does not works

Custom $HOME directories, if you set, for example

HOME=/home/$USER/any/path

or any other path as a custom $HOME directory, GNOME Boxes crashes, or sometime starts but crashes if you download a system.

Steps to reproduce the issue

Open a terminal adn always in the same session:

Create a temporary directory "tmp" we will set as $HOME, then install JuNest and gnome-boxes before (only the following commands, don't close the terminal to have always ./tmp as a custom $HOME, we will use it at point 2), as follow...

mkdir tmp
cd tmp
APP=gnome-boxes
DEPENDENCES="xdg-desktop-portal-xapp xapp"
BASICSTUFF="binutils gzip"
HOME="$(dirname "$(readlink -f $0)")" 
git clone https://github.com/fsquillace/junest.git ~/.local/share/junest
./.local/share/junest/bin/junest setup
./.local/share/junest/bin/junest -- sudo pacman -Syy
./.local/share/junest/bin/junest -- sudo pacman --noconfirm -Syu
./.local/share/junest/bin/junest -- yay -Syy
./.local/share/junest/bin/junest -- yay --noconfirm -S gnu-free-fonts $(echo "$BASICSTUFF $COMPILERS $DEPENDENCES $APP")

Run gnome-boxes in proot mode...

./.local/share/junest/bin/junest proot -n -- gnome-boxes

eventually add flags in "junest -b", these are my defaults

./.local/share/junest/bin/junest proot -n -b "--bind=/home --bind=/home/$(echo $USER) --bind=/media --bind=/mnt --bind=/opt --bind=/usr/lib/locale --bind=/etc/fonts" -- gnome-boxes

How can I solve this?
