I’m having a similar problem but my site looks different than yours.
It’s a scratch site, schindlerscientific.com and I just updated to WP 5.0.2 and updated all of the plugins + integrated reCaptcha v3 according to directions from CF7.
On the CF7 page, the “i am not a robot” box is still there After checking the box and clicking send, I get the failure message.
Further, every page has a recaptca logo in the bottom right which opens up a huge list of things Google is going to do with your info. All true and good to know, but scary. I’ve seen elsewhere ways to remove this, but I’d prefer a simple setting selection somewhere.
