It works fine in GUI-mode. I'm on emacs 29.0.50.

[johnae]

So this may have been because I was running from emacs master. Switching to the latest tag enables a working vterm in tui-mode again. Perhaps we can close this?

[johnae]

So I suppose this could actually be related to running the PGTK variant of emacs. In that version vterm works in GUI-mode (though feels a bit sluggish) but crashes emacs in TUI-mode. Building emacs without wayland-support (eg. the PGTK variant) enables a working vterm in tui-mode.

[mpereira]

I started seeing the same today. I tried running M-x vterm-module-compile but nothing changed afterwards.
