How to repro? Disable for ex. standard model add action in https://github.com/atk4/data/blob/4.0.0/src/Model/UserActionsTrait.php#L122 with 'enabled' => false.
Currently Menu (reproducible in CRUD and CardDeck completely ignores if UA is disabled and renders the executor buttons the same as if enabled:

the UA cannot be correctly executed

but the user should not be able to fill any UA if disabled in the first place
