Ansible Molecule Test Error: cannot reload udev rules: exit status 1 - docker

Question

I'm trying to set up Ansible molecule for testing roles on different OSes. For example, this role is failing when it gets to the task that installs with snap install core:
https://github.com/ProfessorManhattan/Ansible-Role-Snapd
molecule.yml:

install-Debian.yml:
---
- name: Ensure snapd is installed
apt:
name: snapd
state: present
update_cache: true
- name: Ensure fuse filesystem is installed
apt:

ansible.builtin.systemd:
enabled: true
name: snapd
state: started
- name: Ensure snap core is installed # This task is failing
community.general.snap:

The error I receive is:
TASK [professormanhattan.snapd : Ensure fuse filesystem is installed] **********

The same is true for all the other operating systems I'm trying to test. Here's a link to the Dockerfile I'm using to build the Ubuntu image:

Looking for a geerlingguy.
