Can't sudo anymore after hardening

[DoudouJack]

Describe the bug
After running the hardening script, any user using sudo will get "Sorry, please try again" after inputting password

Expected behavior
sudo su -> input password -> switched to root user
or
sudo apt update -> input password -> apt update is executed

Actual behavior

[sudo] password for USER:
Sorry, try again.

where USER is the username having the issue

auth.log output

sudo: pam_unix(sudo:auth): authentication failure; logname=USER uid=1001 euid=0 tty=/dev/pts/0 ruser=USER rhost= user=USER

where USER is the username having the issue

OS / Environment
Ubuntu 20.04.3 LTS (Virtual Machine managed from vSphere)

Ansible Version

ansible [core 2.11.7]

Additional context
This happens with any user, also to newly created ones after the script had been ran. auth.log gives password error, whereas passwords have been checked and newly created for new users. It seems a parameter has been set to not allow sudo to users, even when adding the users to sudo group.
Could you please indicate what change could have modified this behaviour?
Thank you in advance

Can you please share the playbook including any variables you used? Also what version of the collection are you using? Do you use sssd?

We don't modify anything sudo-related.
