Can't enter toolbox on fedora core os

**Describe the bug**

I cannot enter a toolbox using fedora core os. My username here is 'kevin' which is not the default fcos username of 'core'

```
$ toolbox enter
Error: directory /var/home/kevin not found in container fedora-toolbox-39
Using /var/home/kevin instead.
Error: directory /var/home/kevin not found in container fedora-toolbox-39
Error: directory /var/home/kevin not found in container fedora-toolbox-39
zsh: exit 127 toolbox enter
$ toolbox --version
toolbox version 0.0.99.5
$
```

**Steps how to reproduce the behaviour**
unclear, but it happens every time I try to enter the toolbox, and continues to happen even after removing and re-creating the toolbox container.

**Expected behaviour**
I used to have a fedora-toolbox-36 container and I could enter that just fine.
