It’s customary to assign the Solution tag to the reply that answered/solved the original question/problem.
In this case, I explained why your sensor.xxxx_action entities are gone (thereby affecting all automations that used them) and how to fix it, either by modifying the automations to use different triggers (along with a link to a topic with clear examples) or by simply enabling an option that would restore the missing sensors (thereby requiring no modifications).
You acted on this advice and then marked your own post as the Solution.
