Updating failed. The response is not a valid JSON response.

Hello!

I’ve run through most of the suggestions to deal with issues arising from update to WordPress 6.0 but the final one was beyond my technical comfort zone so hoping for help diagnosing the issue I’m facing please.

Prior to the update I’d been using Embeddable Affiliate Widgets from https://uk.bookshop.org/ like this…

<script
      src="https://uk.bookshop.org/widgets.js"
      data-type="book"
      data-affiliate-id="5307"
      data-sku="9781787331235"></script>

…using the following steps in the Visual Editor:

Create classic block
Edit as HTML
Paste in script like below (direct from bookshop.org)

Now when I try to do that I can get the widget to preview by repeatedly pasting the script into a block, choosing the Convert to HTML option from thd dropdown when I’m invited to Attempt Block Recovery.

But when I click Update I get this error: Updating failed. The response is not a valid JSON response.

When I preview in a new tab I just see the script. The existing widgets on my website seem to be working fine. Here are the errors from the Console when I inspet the page:

Any help very much appreciated as I’ve been banging my head for weeks and user support for my host, Bluehost, and Bookshop haven’t been able to help.

Thanks!
