Block not registered

[cena]

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

I encountered this today. Ouch!

Hmm, do anyone have any other reproduction instructions on this?

Plugins/themes used, or maybe steps on how to reproduce it quickly on a clean WP install?

I looked into it (as it was pretty similar to #270, but that issue was related to a compatibility issue with WP 6.4), and I couldn't find any way to reproduce this. :)

Thanks!
