When the check is placed in the parent step and the child step asserts, the check becomes invalid.

@check.check_func
def validate_something(a, b, c, d):
    with allure.step(f'some assertions'):
        with allure.step('aa'):
            assert a == 1
        with allure.step('b'):
            assert b == 2
        with allure.step('cccc'):
            assert c == 13
        with allure.step('dddd'):
            assert d == 4


def test_22():
    with check, allure.step("setup step"):
        assert 5 == 5
    validate_something(1,2,3,4)

or

def validate_something(a, b, c, d):
    with check, allure.step(f'some assertions'):
        with allure.step('aa'):
            assert a == 1
        with allure.step('b'):
            assert b == 2
        with allure.step('cccc'):
            assert c == 13
        with allure.step('dddd'):
            assert d == 4

run the code, the step dddd won't executed , just as below:

I think this is in line with the design expectations.
If your check point are not interdependent. , your code should be follow:

def validate_something(a, b, c, d):
    with allure.step(f'some assertions'):
        with check, allure.step('aa'):
            assert a == 1
        with check, allure.step('b'):
            assert b == 2
        with check, allure.step('cccc'):
            assert c == 13
        with check, allure.step('dddd'):
            assert d == 4

        with check, allure.step('dddd'):
            assert d == 4

I have indeed done this before. if run, the step [some assertions] won't be marked as failed, but passed, and the four sub-steps will be executed, I hope if any sub step is failed, the parent should be marked as failed, and all sub-steps should be executed:

def validate_something(a, b, c, d):
    with allure.step(f'some assertions'):
        with check, allure.step('aa'):
            assert a == 1
        with check, allure.step('b'):
            assert b == 2
        with check, allure.step('cccc'):
            assert c == 13
        with check, allure.step('dddd'):
            assert d == 4


def test_22():
    with check, allure.step("setup step"):
        assert 5 == 5
    validate_something(1,2,3,4)

I'd consider this a feature request, to support allure.step() in conjunction with check.

I would look at a PR for this, but since I don't use allure, I don't have plans to work on this.
I'd also want any changes to not affect performance negatively.
