How do I I open a construct game because addons don't exist anymore.?

So I was working on a construct project that had the addons UTILS and BETTERINPUTMANAGER which I wasn't using but forgot to delete. Now I can't open my project because it says:

The only problem is I cant add them because construct removed them from the website.

I still have the project folder, is there a way I can delete the addons from there?

The addons are still there on the addon exchange, you need to uncheck the show sdk v2 addons only checkbox. it seems like it's enabled by default since like a day or so.
