selectattr returns generator rows and cannot use results as a dict

Question

SOLUTION: I Don't know what is the exact difference between python -m pip install ansible or apt install ansible but when I installed python -m pip ansible-core==2.10.4 it works fine.

I have CSV file which looks like:

id;env;credentials;path
1;tst;userA;/tmpA
2;dev;userB;/tmpB
3;dev;userB;/tmpC
4;acc;userB;/tmpD
5;prd;userC;/tmpE

I read this file using read_csv module and then I'm filtering using selectattr:

  - name: Read CSV
    read_csv:
      path: "/tmp/example.csv"
      delimiter: ';'
    register: csv_output

  - name: Filter rows
    set_fact:
      new_fact: "{{ csv_output.list | selectattr('env', 'equalto', tst) }}"

In the past I was able to just use these results as a dict so for example:

- debug:
    msg: "{{ new_fact }}"

ok: [ansible_main] => {
    "msg": [
        {
            "id": "1",
            "env": "tst",
            "credentials": "userA",
            "path": "/tmpA"
        }
    ]
}

but when I try to print new_fact on my local machine I see only generator:

ok: [ansible_main] => {
    "msg": "<generator object select_or_reject at 0x7f2e4e8847b0>"
}

and I cannot use new_fact.credentials variable... Do you know how can I fix it? I know I can add | list at the end of my filter but then I also cannot use new_fact.credentials
