Description
When opening a post where I'd previously used a SHE block, I now see this:

Plugin in active and installed. I also tried installing the Gutenberg plugin which didn't affect anything.
Strangely, it still seems to be working on the frontend:

---
WP 6.1.1
TwentyTwelve
TwentySeventeen
Storefront
SyntaxHighlighter: 3.6.2

Research direction
Start by reproducing the issue in the WordPress editor with an existing SHE block, using the reported WordPress and plugin versions, and compare it with the working frontend rendering. Done means previously saved SHE blocks are registered and editable without the unregistered-block warning while their frontend output remains unchanged.
