I have fixed it with this PR #2756

@girishpanchal30, using the free version from this PR, now I can publish the post; however, if I go and change the Post Content to Excerpt, I get a fatal error (when testing on TasteWP i see the fatal error).
I'm not sure if this issue occurres with the current version too, as I can't publish the post to test it.

@girishpanchal30 that is working now. However, when I try a simple use case, with Neve PRO's Custom Layouts, for the single post page, this doesn't seem to work anymore.
In the video, I've shown how it looks with the current version of Otter, and what happens when I use the version from this PR
