It's already reviewed, something strange was broken my fork. #44622

To get rid of the error on the GuardEvent, you need to add the @param annotation to its constructor.

        /**
         * {@inheritdoc}
         *
         * @param TSubject $subject
         */
        public function __construct(object $subject, Marking $marking, Transition $transition = null, WorkflowInterface $workflow = null, array $context = [])

Thanks, resolved!

The failure is legit.
Please don't forget to patch the .github/expected-missing-return-types.diff file as done eg in #44695 (see the file for how)
Note that since DebugClassLoader is not able to understand the @template annotations (yet), I added a hack in 1dad23b
We're going to need something similar here (or to patch DebugClassLoader before merging.)

Good idea, i will check how i can do it in this case.

Can't find solution for your suggestion. I close PR.
