Can’t use recipe plugin since update to 4.5.1

Before I updated to the last gutenberg version the wp recipe maker plugin was available in the blocks but now this block is no longer available.
The recipes I already posted are luckily shown in the right way but I can’t add a new recipe post or change the former ones made with gutenberg cause on the one hand the block is no longer available and on the other hand instead of the recipe block text the following message is shown: your website does not support “wp-recipe-maker/recipe”-Block. You could either leave the block like it is or you could delete it completely.”

The recipe plugin works if I create a new post in the classic editor. But this is only a solution for new posts but not for the old ones.
Please let me know how and when this problem will be fixed.

And another question: what would happen if I would now deactive the gutenberg plugin? what happens with the recipe posts already created with gutenberg before the update to 4.5.1?

Thanks.
