Block Editor Crashes in New / Edit Post

Resolved

(@conquerorintraining)

I just updated to WP 6.0, and now the “block editor” crashes WP (either editing an existing post, or adding a new one). The editor is extremely slow to load, and when it finally does, it crashes when I try adding a block.

I’ve tried disabling all themes, plugins, enabling / disabling the visual editor, and manually reinstalling WP (I initially updated through the WP-Admin). All plugins / themes are up to date (though disabled now). I’ve also tried clearing browsing data, and using both Chrome and Firefox – it doesn’t work in either browser.

I managed to find this error after a crash, and it seems to indicate a Javascript issue in the core WP files, but I don’t know what’s causing it or how to fix it:

TypeError: Cannot destructure property 'possibleBlockTransformations' of '(0 , m.useSelect)(...)' as it is undefined.

I’m not sure what else to try. Any help is appreciated, thank you.

I’ve finally managed to switch from the “visual editor” to the “code editor” view, and that seems to work perfectly well. This is only a workaround though, and hasn’t actually fixed the original problem.

I also got a variant of the error now:

TypeError: Cannot destructure property 'patternCategories' of '(0 , m.useSelect)(...)' as it is undefined.
