All right, any WordPress experts out there?

I want to just write my posts in raw HTML.  The Block Editor appears to be not working for me (I mean, not even working as it's supposed to -- even if it were it wouldn't be what I'd want to use), and Classic Editor ditto.

I see that there are a few plugins for this, but most of them appear to be out-of-date w.r.t. the latest WordPress, and the couple that weren't I tried -- and they didn't work at all in the way I wanted.

I just want to write HTML.  (Why is the platform so resistant to that?)

To be clear:

By "any WordPress experts out there", I mean that I'm happy to hire you at your consulting rate.
