Same issue here. I hope for a quick fix as have multiple sites using a lot of Gutentor features, it would be a pain to redo them all!
“As a temporary measure, you may want to consider deactivating the Gutentor plugin while awaiting a resolution. This will enable you to continue editing your content using the default Gutenberg blocks without encountering errors.”
That works but it is not the most ideal solution. Good luck fixing the issue, we hope all will be ok soon!
