Generate blocks acting weird

Hi there,

I've been using generatepress with generateblock very happily over the past months. Suddenly today when I open one of my posts on wordpress block editor, I see an error that the container block isn't installed (which it is). I use container blocks everywhere, so I quickly check the generateblocks plug in, but the whole plug in seems to be not working properly this morning. I have attached screenshots so you can get a better picture of what I mean.
I simply cannot understand it. Help please.

Thanks
Kumar
