Error: Failed to execute ‘removeChild’

I’m getting this error on a client’s website that uses Beaver Builder Lite. The client says the post editor keeps crashing when using the standard editor, but the error seems to be related to the React library and I think Beaver Builder uses React, so think this might be the right place to ask.

Error:

Error: Failed to execute ‘removeChild’ on ‘Node’: The node to be removed is not a child of this node.
