Extendify crashes the editor when I try to insert a Kadence Row Layout

Since my site updated to 5.9, both this plugin and the EditorsKit plugin which I previously had installed crash the editor when I try to insert a Kadence Blocks Row Layout–a block I use A LOT. There is no problem with the Kadence block if I deactivate Extendify or EditorsKit. This is the error message I get:

TypeError: Cannot read properties of undefined (reading 'className')

I’d like to be able to have access to the Extendify library on this site, but trust me, if I have to make a choice, I’m going to choose Kadence.
