Toggle Blocks not working after update

After updating the Portfolio gallery plugin and then WordPress, the toggle blocks no longer loaded — just showed the loading icon.

I deleted the widget, put it back anew, turned off the loading icon, now the blocks loaded as if set to Full-Height Blocks, and ran over the text below. If I set the blocks to FAQ Toggle, they load correctly, but do not toggle. The only way I can get my content to load at all is to set it to Full-Height Blocks, which doesn’t look great and is not the reason I chose this plugin.

Please help — how do I get the toggle functionality back?
