Editing window now blank

Hi there, I don’t know if this is Otter Blocks causing this, but the onboarding suggests it might be. It could be the Neve template.

I have a WordPress site which might be set to automatically update, so I don’t know when the error began happening. Possibly when it went to WordPress 7 since the start of May.

The editing window is now blank. I can’t see what I’m editing. I’ve tried three browsers (both Chromium- and Firefox-based). The input is being accepted as some fields change, but the text is white on white.

I have updated all the plug-ins so everything is current. Is this something you can advise me on, please?
