Can’t create a post

Hi!

Starting a few days ago, I get an “unexpected error” any time I try to add or edit a block in a new post. I have tried to disable plugins to no avail. The exact error is below. Any help is appreciated more than you know.

TypeError: Cannot destructure property 'possibleBlockTransformations' of 'Object(...)(...)' as it is undefined.
