Blank page after adding block

Hi there,
we have 2 console errors after adding a TOC block:
wp.data.select( 'core/editor' ).getBlocks is deprecated. Please use wp.data.select( 'core/block-editor' ).getBlocks instead.
Ae — blocks.min.js:3:92476
The block “gutentoc/table-of-contents” is registered with an invalid category “gutentoc”.

And after saving page and reloading we get a blank page. No errors in debug.log.
