Thanks! I dived into the issue a bit more, and it seems like the problem lies in the default mapping in /etc/subuid file.
The first OS regular user created usually has the assignment 100000:65536 in /etc/subuid.
I decided to assign the values (231072:65536) from the user that succeed with the podman pull command to the user with previous 100000:65536. With the new values, podman (and therefore, clickman) runs without issues.
I don't see any conflict on the default range assigned, but definitely that new assignment seems to fix it.
Hope it helps for those that run into it
