For VirtualBox to function you need to identify your kernel
Example
$ uname -r
6.14.1-1-MANJARO
Please adjust the commands to match your kernel. Then you choose
either dkms, kernel headers and vbox host modules
sudo pacman -Syu linux614-headers dkms virtualbox-host-dkms
or the appropriate host modules for the running kernel
sudo pacman -Syu linux614-virtualbox-host-modules
Only then will it be possible to use virtualbox
sudo vboxreload
