Anbox does not start. Please help

I click anbox in the menu and I get a starting screen but it goes a way after a while and it seems like nothing happens. I’m pretty sure I followed all the indications.

Kernel: 5.10.36-2-MANJARO

I have the following installed:

$ sudo pacman -Q | grep anbox
anbox-git 1:r1346.7d1930c-1
anbox-image 1:2018.07.19-1

I did this:

mkdir /dev/binderfs
mount -t binder binder /dev/binderfs

Added this to /etc/fstab :

binder    /dev/binderfs    binder    nofail    0    0

Also did this:

systemctl enable anbox-container-manager.service
systemctl enable systemd-networkd anbox-container-manager

I did this later on as well:

systemctl --user enable --now anbox-session-manager.service

My /dev looks like this:

$ ls -1 /dev/{ashmem,binder}   
ls: cannot access '/dev/binder': No such file or directory

$ ls -1 /dev/{ashmem,binderfs}


Running anbox session-manager returns the following:
