It appears the relevant lines of the log are:

I tried to fix this one, but I have been completely unable to make any progress so far.

Need the big guns here...

Maybe it is time to switch to a newer fork of ManOpen, such as: ​https://github.com/nickzman/ManOpen. The Xcode project for ManOpen 3.0 builds and runs for me on Ventura.

ManOpen 3.x is based on ManOpen 2.x by Carl Lindberg, and ManOpen 1.x by Harald Schlangmann. This version has been greatly enhanced, with a new UI for macOS 11 ("Big Sur"), support for Dark Mode, native support for Apple Silicon Macs, plus several internal refactors and rewrites so the app will run on modern macOS releases. ManOpen requires macOS 10.9 ("Mavericks") or later.

Looks like he found out ​why cat2html was failing and fixed it.

But ManOpen, by default, won't work on Ventura due to the removal of nroff. In order for it to work, you'd have to either:

1. Point ManOpen to the path of MacPorts' nroff.
2. Use mandoc.

And yes, this does include nickzman's fork.
