@wetternest hi. I had the same problem. Try to update packages @types/prosemirror-model, @types/prosemirror-commands, @types/prosemirror-inputrules, @types/prosemirror-state to the last version. It helps me. And [#2551](https://github.com/nhn/tui.editor/issues/2552) fixed as well

`"@types/prosemirror-model": "^1.16.2", "@types/prosemirror-commands": "^1.0.4", "@types/prosemirror-inputrules": "^1.0.4", "@types/prosemirror-state": "^1.3.0",` When update packages try to remove node_modules folder and then run `npm i` again
