if you have it downloaded onto your computer and your Patreon membership expires, I THINK the current version that you downloaded when you had the membership would still be on your computer, Im not sure though, but I think it still would be on your computer/PC.
You can continue playing whichever current version of the game you have downloaded, but you won't be able to download the latest versions whenever they are released, unless they decide to post them on itch
