The small piston goes up and down by the camshaft, remaining stuck up

I released the piston I cleaned it and oiled it and now the engine is back to working properly

my question :

Do you also have an event like this?

And what do you think should be done to prevent this problem from coming back?

I've never had that happen. How much running has it done? It maybe a heat issue, causing it to jam?
As long as the lifter is moving free, there's not a lot more you can do.
If it does it again, I would replace the lifter.
